Overview
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.
Every standard and custom field arrives verified.
AI proposes the map; you confirm before any record moves.
Parent–child, lookups, and ownership stay linked.
Calls, emails, meetings — with original timestamps.
Documents, uploads, and inline notes move with the record.

Object mapping
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
Trello
Board
1:1Celoxis 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
Trello
Card
1:manyCeloxis 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
Trello
Card Dependency (Power-Up)
lossyCeloxis 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)
Trello
Board Member
1:1Celoxis 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
Trello
Card Custom Fields (Power-Up)
lossyCeloxis 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
Trello
Card Attachments
1:1Celoxis 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
Trello
Card with Label
lossyCeloxis 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
Trello
Workspace or Board Group
lossyCeloxis 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
Trello
Not supported
1:1Celoxis 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
Trello
Not supported
1:1Celoxis 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
Trello
Not supported
1:1Celoxis 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
Trello
Card with Label
lossyCeloxis 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
Trello
Not supported
1:1Celoxis 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
Trello
Not supported
1:1Celoxis 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.

API rate limits are token-gated and can block bulk migration
Guest-to-paid seat conversion triggers on multi-board membership
Automation command runs are capped per plan and overage triggers upgrade pressure
Pair-specific challenges
Migration approach
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.
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.
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.
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.
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.
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.
