Overview

What this migration involves

Moving from Celoxis to Trello is a deliberate simplification. Celoxis bundles enterprise PPM features — multi-baseline Gantt scheduling, resource workload management, cost and billing rate models, timesheet approval workflows, and risk tracking — into a single platform priced from $25 per user per month plus $5 per user per month for financial modules. Trello operates at the task-card level with no native financial model, no resource management, and no Gantt dependency visualization. We map Celoxis Projects to Trello Boards, Tasks to Cards, subtasks to checklists or child cards, task dependencies to Card Dependencies Power-Up cards, and custom fields to Trello card-level custom fields. We do not migrate Celoxis financial records, timesheets, expenses, baselines, risks, issues, job roles, or dashboards as these have no Trello counterpart. We deliver a written object inventory of every Celoxis object and field for your admin to review before migration scope is finalized.

Field-level fidelity

Every standard and custom field arrives verified.

Schema-aware mapping

AI proposes the map; you confirm before any record moves.

Relationships preserved

Parent–child, lookups, and ownership stay linked.

Full activity history

Calls, emails, meetings — with original timestamps.

Attachments & notes

Documents, uploads, and inline notes move with the record.

Why teams make this switch

Two sides of the same decision

Leaving

Celoxis logo

Celoxis

What's pushing teams away

  • New users find Celoxis difficult to learn — the depth of features creates a steep onboarding curve that frustrates smaller teams or less experienced PMs.
  • The user interface is widely described as dated, and the platform lacks a native mobile app, limiting usability for field or remote teams that need mobile access.
  • Feature richness becomes a drawback for simpler projects — teams using Celoxis for basic task management feel they are paying for capabilities they never use.
  • The pricing model charges extra for what many competitors bundle: Risk Management, Timesheet, Expense, and Billing are paid add-ons at +$5/user/month on top of the base tier.
  • Support quality is tiered — lower plans receive community-only support, which frustrates customers expecting consistent service across all tiers.

Choosing

Trello

What's pulling them in

  • Free plan supports unlimited users and 10 boards, giving small teams full access to core Kanban functionality before any paid commitment is required.
  • The drag-and-drop board/card/Label interface requires no training, which reduces adoption friction and onboarding time across distributed teams.
  • Atlassian ecosystem integration with Jira, Confluence, and Bitbucket provides native cross-tool workflows for teams already using Atlassian tools.
  • Butler automation on paid tiers enables rule-based triggers without third-party integrations, covering basic workflow automation needs.
  • Simple visual task management with due dates, checklists, and member assignments keeps individual contributors and small teams organized without complexity.

Object mapping

How Celoxis objects map to Trello

Each row shows how a Celoxis object lands in Trello, including any object-level transformations, lookup resolution, or schema-design dependencies.

Typical mapping — final map is confirmed during the sample migration step.

Celoxis

Project

maps to

Trello

Board

1:1
Fully supported

Celoxis Projects map directly to Trello Boards. Project name, description, start date, and target date migrate to Board name, Board description, and the first Card's due date for date anchoring. Celoxis Data Isolation workspaces map to separate Trello workspaces if the source account uses Celoxis Enterprise multi-workspace mode. Celoxis sub-projects map to child Boards via Trello Board Links Power-Up or a parent Board with a sub-Board list, depending on complexity at scoping.

Celoxis

Task and Subtask

maps to

Trello

Card

1:many
Fully supported

Celoxis Tasks map to Trello Cards. Celoxis subtasks map to child Cards in the same Board or to checklist items within the parent Card — we determine the preferred strategy during scoping based on subtask depth. Celoxis task status (Not Started, In Progress, Completed) maps to Trello List position (To Do, Doing, Done) with a default three-list structure, customizable per Board. Celoxis split tasks and recurring tasks are noted separately as they have no Trello native equivalent and require manual rebuild if critical.

Celoxis

Task Dependency

maps to

Trello

Card Dependency (Power-Up)

lossy
Fully supported

Celoxis finish-to-start, start-to-start, finish-to-finish, and start-to-finish task dependencies map to Trello Card Dependencies Power-Up (Atlassian-native) which supports blocking and blocking-with-date propagation. We reconstruct the dependency graph from Celoxis and configure the Power-Up relationships during migration. Lead-lag time is preserved in the dependency notes field since Trello does not natively support lead-lag. Celoxis critical path data is noted in a separate document for the customer admin to re-establish using Trello Timeline Power-Up if needed.

Celoxis

Resource (User)

maps to

Trello

Board Member

1:1
Fully supported

Celoxis Resources map to Trello Board Members. We resolve Celoxis users by email address and invite them to the corresponding Trello Board. Celoxis resource cost rates and billing rates have no Trello equivalent and are not mapped. Job Roles (role templates with associated cost rates) do not migrate; we deliver a role inventory for the customer admin to document outside Trello. Any Celoxis Resource not matched to a Trello user goes to the reconciliation queue.

Celoxis

Custom Fields

maps to

Trello

Card Custom Fields (Power-Up)

lossy
Mapping required

Celoxis custom fields defined on Projects and Tasks map to Trello Custom Fields Power-Up on each Board. We match by name and map Celoxis field types (text, number, date, dropdown, checkbox, user reference) to Trello Custom Field types. Celoxis allows 25–1,000 custom fields depending on tier; Trello custom fields are per-card, not per-board, so the customer admin may need to choose which fields apply per-card during configuration. Custom fields defined on Celoxis Resources are not migrated as Trello has no resource-level custom field concept.

Celoxis

Documents and Attachments

maps to

Trello

Card Attachments

1:1
Mapping required

Celoxis project and task attachments migrate to Trello Card Attachments. We extract the file URL or binary from Celoxis and attach it to the corresponding Card. Celoxis document metadata (name, description, upload date, uploader) migrates as card attachment metadata. Celoxis v15 note: document body full-text search was removed; Trello card attachments are stored as-is without indexing. If the customer relies on document content search, we flag this gap and recommend a Trello-integrated search tool (Confluence, Google Drive) post-migration.

Celoxis

Issue

maps to

Trello

Card with Label

lossy
Fully supported

Celoxis Issues (separate from Risks) with status, assignee, and linked project map to Trello Cards with a dedicated Issue label. We preserve the Celoxis issue description, priority, and status as card description and Trello label color. Issue workflow states (Open, In Progress, Resolved, Closed) map to List position or label subsets depending on the source workflow complexity.

Celoxis

Portfolio

maps to

Trello

Workspace or Board Group

lossy
Fully supported

Celoxis Portfolios group multiple Projects under a strategic hierarchy. These map to Trello Workspaces (Enterprise tier) or a Board group with a naming convention (Portfolio-Project). Portfolio-level KPIs, aggregated financial views, and cross-project resource utilization do not migrate — Trello has no portfolio aggregation concept. We document the portfolio hierarchy as a reference map for the customer admin to recreate manually in Trello if required.

Celoxis

Timesheet

maps to

Trello

Not supported

1:1
Fully supported

Celoxis Timesheet records (billable and non-billable time entries with activity codes and approval states) do not migrate. Trello has no timesheet module. Timesheet data is exported to CSV as a reference document for the customer admin to import into a separate time-tracking tool (Toggl, Harvest, or a native Trello Power-Up) if needed. The Celoxis Professional plan includes Timesheet as a standard feature; this object exists in most Celoxis Professional and Business accounts. We verify Timesheet add-on status at scoping.

Celoxis

Expense

maps to

Trello

Not supported

1:1
Fully supported

Celoxis Expense records (with expense codes, reimbursable flags, and approval workflows) do not migrate. Trello has no expense tracking capability. We export expense records to CSV with codes, amounts, and reimbursable status as a reference for the customer admin. The approval workflow state is not exportable and must be re-established in the destination tool.

Celoxis

Baseline

maps to

Trello

Not supported

1:1
Fully supported

Celoxis multiple baselines per project (unique among PM tools) do not migrate. Trello has no baseline concept. We capture all baseline snapshots as a JSON reference file so the customer can compare planned vs. actual performance outside Trello. If baseline comparison is required post-migration, we recommend a Trello-integrated reporting tool (Power-Ups or a data warehouse export).

Celoxis

Risk

maps to

Trello

Card with Label

lossy
Fully supported

Celoxis Risks with severity, probability, and mitigation fields migrate to Trello Cards with a dedicated Risk label. Risk Management is a paid add-on at +$5 per user per month on Celoxis Professional; we verify add-on status at scoping and adjust migration object list accordingly. If active, we preserve risk severity and probability as Trello label colors and custom field dropdowns on the Risk card. Risks without the add-on do not exist in the source account.

Celoxis

Dashboard and Report

maps to

Trello

Not supported

1:1
Fully supported

Celoxis aggregated dashboards, cross-project KPIs, and financial reports do not migrate. Trello does not support native cross-board reporting dashboards (Power-Ups like Blue Cat Reports offer basic visualization, but native dashboards are not part of the core product). We export report data to CSV and deliver a report inventory with field definitions and row counts. Dashboard widget configuration (layout, chart types, date ranges) cannot be imported and must be rebuilt in Trello Power-Ups or an external reporting tool.

Celoxis

Custom App

maps to

Trello

Not supported

1:1
Fully supported

Celoxis Custom Apps (custom record types with their own fields, forms, and workflows, available on Business and Enterprise tiers) do not migrate. We export the data stored in custom app records as a flat CSV but cannot transfer the app definition itself. Customers must rebuild the app structure in the destination system. We provide a custom app field inventory (name, type, options) as a re-implementation guide.

Pair-specific challenges

  • Financial data has no Trello destination

    Celoxis stores cost rates, billing rates, project budgets, cost-vs-actual comparisons, and time-code billing rules. Trello has no native financial model — no cost fields, no billing rates, no budget tracking. If the migration includes projects with fixed-price or time-and-materials billing configurations, those rates, budgets, and financial milestones are not transferable. We export all financial object records to CSV for reference and note every financial field in the mapping document, but the customer must decide whether to maintain financial tracking outside Trello (in a spreadsheet, ERP, or a financial Power-Up) or accept that Trello cards carry only task status and due dates.

  • Task dependencies require a Power-Up

    Celoxis stores four dependency types (finish-to-start, start-to-start, finish-to-finish, start-to-finish) with lead-lag time. Trello's native Card Relationships feature does not exist in the free tier and is limited even in Premium. The Trello Card Dependencies Power-Up (Atlassian-produced, $5 per workspace per month) must be enabled on the destination workspace for dependency relationships to function. We configure the Power-Up during migration and map Celoxis dependencies to blocking or blocked-by relationships, but lead-lag time is stored as a card note only. If the team relies on Gantt-style schedule propagation, a Trello Timeline Power-Up or a third-party Gantt integration is required separately.

  • Paid add-ons gate Risk, Timesheet, and Expense objects

    Celoxis Risk Management, Timesheet, Expense, Costing, and Billing are not included in the base tier — they are paid add-ons at +$5 per user per month. If the source Celoxis account does not have these add-ons active, the corresponding records will not exist to migrate. We verify add-on status at scoping and adjust the migration object list. Migrations from Celoxis Essential (which has no financial modules) will have no Risk, Timesheet, or Expense records regardless of the migration scope.

  • Custom Apps do not migrate as apps

    Celoxis Business and Enterprise tiers allow fully custom record types with their own fields, forms, and workflows. Custom Apps are Celoxis-specific platform constructs. We export the data stored in custom app records as CSV, but the app definition (form builder, workflow logic, custom field definitions) cannot transfer to Trello. Customers must rebuild the app structure. We provide a custom app field inventory with field names, types, and picklist options to assist with re-implementation in Trello Power-Ups or a separate tool.

  • Document full-text search removed in Celoxis v15

    Starting with Celoxis v15 (November 2025), document body content is no longer indexed for search. Document search now matches only on metadata (name, description). Advanced search operators (+A must-include, -B must-exclude) are also no longer supported. If the customer relies on document content search, we flag this gap at scoping and recommend a post-migration document search strategy using Trello-integrated Google Drive or Confluence search.

Migration approach

Six steps for a successful Celoxis to Trello data migration

  1. Discovery and add-on audit

    We audit the source Celoxis account across tier (Essential, Professional, Business, Enterprise), active add-ons (Timesheet, Expense, Costing, Billing, Risk Management), Celoxis version (checking for v15 document search changes), custom field schemas on Projects and Tasks, custom app definitions, and attachment volume. We pair this with a Trello workspace readiness check: confirming the destination Trello plan supports the required Power-Ups (Card Dependencies, Custom Fields), verifying workspace admin access, and identifying any Trello Enterprise requirements if the team exceeds 500 members. The discovery output is a written migration scope that explicitly lists every object that migrates and every object that does not.

  2. Board structure design and dependency Power-Up setup

    We design the Trello board architecture based on the Celoxis project hierarchy. Each Celoxis Project becomes a Trello Board with a three-to-five List default structure (To Do, In Progress, In Review, Done). Celoxis sub-projects and phases map to child Boards or Lists depending on depth. We enable the Card Dependencies Power-Up on the workspace and configure the default dependency type (blocking). We map Celoxis custom fields per Board, choosing per-card vs. per-board application based on the customer's field usage patterns observed during scoping.

  3. Sandbox migration and reconciliation

    We run a full migration into a test Trello workspace using production-like data volume. The customer's project lead reconciles board structure (Boards match Projects), card completeness (Cards match Tasks), subtask mapping (checklists vs. child cards), attachment counts, and dependency relationships. We validate that all Celoxis task assignments have corresponding Trello Board members and that Celoxis custom field values map to Trello custom field options correctly. Any structural corrections happen here before production migration.

  4. User provisioning and member mapping

    We extract every distinct Celoxis Resource referenced on tasks and map them to Trello workspace members by email address. We flag any Celoxis Resource without a matching Trello account for the customer admin to provision before migration resumes. Celoxis cost rates and billing rates are extracted as a reference file but are not applied to Trello members (Trello has no resource cost model). Job Role definitions are exported as a role inventory document.

  5. Production migration in dependency order

    We run production migration in record-dependency order: Workspace and Boards (from Celoxis Projects), Board Members (from Celoxis Resources), Cards (from Celoxis Tasks), Checklists or child Cards (from Celoxis Subtasks), Custom Fields (configured per Board), Card Attachments (extracted from Celoxis Documents), Dependencies (configured via Card Dependencies Power-Up), Risk cards (with Risk label and severity/probability custom fields), and Issue cards (with Issue label). Financial records (Timesheet, Expense, Costing, Billing) are exported to CSV and referenced but not created in Trello. Each phase emits a row-count reconciliation report before the next phase begins.

  6. Cutover, validation, and automation rebuild handoff

    We freeze Celoxis writes during cutover and run a final delta migration of any tasks modified during the migration window. We enable Trello as the active project management system. We deliver the written automation inventory documenting any Butler rules the customer wants to configure for recurring task generation, due date propagation, or card moves. We do not configure Butler rules as part of the migration scope — we provide the trigger and action inventory for the customer's Trello admin. We support a one-week hypercare window to resolve any card attachment or mapping issues raised by the team.

Platform deep dives

Context on both ends of the pair

Celoxis logo

Celoxis

Source

Strengths

  • Integrated financial tracking with project-level cost rates, billing rates, and budget vs. actuals in a single view.
  • Multi-baseline scheduling with critical path analysis built directly into the interactive Gantt chart.
  • Resource workload and conflict management with capacity visualization across the portfolio.
  • Tiered API with up to 1800 requests/hour on Enterprise for high-volume integrations.
  • Both cloud (SaaS) and on-premise (Linux + PostgreSQL) deployment options.

Weaknesses

  • No native mobile app — mobile users must access via a browser which offers limited functionality.
  • Dated UI compared to newer PM tools; visual design has not kept pace with modern UX expectations.
  • Steep learning curve for new users — the depth of features overwhelms teams used to simpler tools.
  • Risk Management, Timesheet, Expense, and Billing are paid add-ons rather than core features.
  • Full-text document search was removed in v15 — document content is no longer indexed, only metadata.

Trello

Destination

Strengths

  • Generous free tier with unlimited users and 10 boards, the lowest barrier to entry among major project management tools.
  • Intuitive drag-and-drop Kanban interface requires no training or onboarding documentation.
  • Deep Atlassian integration with Jira, Confluence, and Bitbucket for teams already in the ecosystem.
  • Built-in Butler automation covers rule-based triggers without requiring third-party integrations.
  • REST API with comprehensive documentation enables programmatic access to all core objects.

Weaknesses

  • Reporting and analytics are absent, with no built-in velocity tracking, burndown charts, or historical performance metrics.
  • The flat board/list/card data model scales poorly for complex projects requiring hierarchical task structures.
  • Customization is limited compared to platforms like Asana, monday.com, or Jira that offer richer field types and workflow configuration.
  • Advanced views (Timeline, Dashboard) require Premium and are not available on Standard, inflating total cost for teams needing visibility features.
  • Guest user billing rules are confusing and prone to accidental seat overages when guests join multiple boards.
