Overview

What this migration involves

Moving from ONES.com to Trello is a significant model simplification: ONES is a full-lifecycle software development platform with sprint planning, bug tracking, test-case management, requirements traceability, and CI/CD integration; Trello is a Kanban board tool built around Boards, Lists, and Cards with optional Power-Up custom fields. We migrate the work-item layer (Projects, Tasks, Bugs, Requirements, Sprints) as structural equivalents and flag that Sprints, Requirements, TestCases, and automation rules require explicit rebuild decisions in Trello before migration. Wiki pages migrate as Card attachments with wide-table pages exported as Word (.docx) rather than PDF to avoid silent truncation. ONES automation rules and pipeline configurations do not migrate; we deliver a written inventory of each for the customer's admin to rebuild in Trello Butler and the destination CI/CD platform respectively.

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

ONES.com

What's pushing teams away

  • Interface complexity and learning curve can be steep for non-technical team members, especially compared to simpler project management tools.
  • Performance slowdowns reported on larger projects with extensive task histories, particularly in the on-premises version.
  • The platform is opinionated toward software development workflows, making it less flexible for non-technical project management use cases.
  • Limited third-party integrations outside the Atlassian ecosystem compared to general-purpose project management platforms.

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 ONES.com objects map to Trello

Each row shows how a ONES.com 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.

ONES.com

Project

maps to

Trello

Board

1:1
Fully supported

ONES Project maps directly to a Trello Board. The project name becomes the board title, and project description maps to the board description field. We set the board visibility (private, team, public) based on any ONES project visibility settings, defaulting to private if no explicit setting exists. Each ONES Project with active tasks and bugs becomes a dedicated board; if the customer prefers consolidated boards by team, we offer a workspace consolidation strategy during scoping.

ONES.com

Task

maps to

Trello

Card

1:1
Fully supported

ONES Tasks migrate as Trello Cards. The task title becomes the card name, description migrates as card description (with ONES rich-text converted to Trello's markdown subset), assignees map to Trello members by email, due dates map directly, and priority labels map to color-coded Labels (High=red, Medium=yellow, Low=green). Subtasks in ONES become Checklist items on the parent Card in Trello, preserving the parent-child relationship. Task status in ONES (To Do, In Progress, Done) maps to card position within the relevant List, or to a dedicated Done list.

ONES.com

Bug

maps to

Trello

Card (with Label)

1:1
Fully supported

ONES Bugs migrate as Trello Cards with a Bug Label applied for visual differentiation. Severity (Critical, Major, Minor) migrates as a Trello Label color; steps-to-reproduce and environment fields migrate as card description sections. The link between Bug and parent Task in ONES maps to the Card's Checklist or to a Card link if Trello Card Peek is available. Bugs in ONES are often tracked on a separate Bug board; we offer either a dedicated Bug board or a Bug Label filter on the main board as the customer prefers during scoping.

ONES.com

Sprint

maps to

Trello

Due date range + List or Label

lossy
Fully supported

ONES Sprints have start date, end date, goal, and task membership with no direct Trello equivalent. We map Sprint assignment in one of two ways, chosen during scoping: as Card due dates (set to the Sprint end date) with a Sprint name Label, or as a dedicated List per Sprint within the board. The Sprint start date is preserved in a custom field if the Trello Standard or Premium Power-Up custom fields are active. We note that Trello has no native sprint velocity or burndown tracking; these must be rebuilt in Trello reports or a third-party analytics Power-Up post-migration.

ONES.com

Requirement

maps to

Trello

Card (with Requirements Label)

lossy
Fully supported

ONES Requirements are distinct work items capturing product specifications and linking to Tasks and TestCases. Trello has no native Requirements object, so we map Requirements to Cards with a Requirements Label. The linkage between Requirement and child Tasks in ONES is preserved by placing linked Tasks as Cards in the same List or by adding a Checklist on the Requirement Card listing linked task titles. Requirements with no linked tasks migrate as standalone Cards with a Requirements Label and description content preserved.

ONES.com

TestCase

maps to

Trello

Card (with checklist steps)

lossy
Fully supported

ONES TestCases contain test steps, expected results, and pass/fail history linked to Requirements and Builds. Trello has no native test-case management, so we map each TestCase to a Card with a TestCase Label. The test steps and expected results migrate as a Checklist with step number, description, and expected result as the checklist item text. Pass/fail status and last-run date migrate as custom fields (Standard or Premium Power-Up required). TestCase-to-Requirement links in ONES are preserved as a Checklist on the Requirement Card listing linked test case titles.

ONES.com

Wiki Page

maps to

Trello

Card attachment or external link

lossy
Fully supported

ONES Wiki pages migrate as Card attachments in Trello. We export page content as a Word (.docx) file rather than PDF because ONES Wiki PDF export silently truncates tables exceeding approximately 720px width. The .docx attachment links to the Card representing the related work item. If the Wiki page has no linked work item, we create a standalone Card with the page title as the Card name and the .docx as an attachment. Page tree structure in ONES Wiki is preserved as a Card checklist or a linked board structure if the customer requests it during scoping.

ONES.com

User / Member

maps to

Trello

Member

1:1
Fully supported

Project members in ONES map to Trello members by email address. We extract every distinct email referenced on Tasks, Bugs, TestCases, and wiki pages, then match against the Trello workspace members. Members without a matching Trello account go to a reconciliation queue for the customer's admin to provision before record migration. ONES role-based permissions (Owner, Admin, Member, Guest) do not map directly to Trello roles; we recommend a Trello workspace role audit post-migration to align with the customer's desired access model.

ONES.com

Custom Field

maps to

Trello

Power-Up Custom Field

lossy
Fully supported

ONES custom fields on Tasks, Bugs, and TestCases (dropdown, text, number, date, user reference) map to Trello Power-Up custom fields if the customer has Trello Standard or Premium. Trello Standard includes custom fields as a native Power-Up; Premium adds additional field types and board-level custom fields. We flag during scoping whether the destination workspace has the required plan, and we note that custom field data that does not fit Trello's type model (for example, ONES multi-select user references) may require a text representation or a separate tracking approach in Trello. Custom fields are migrated as text if Trello Premium is not available.

ONES.com

Attachment

maps to

Trello

Card attachment

1:1
Fully supported

Attachments on ONES Tasks, Bugs, and Wiki pages are downloaded from ONES storage and re-uploaded as Card attachments in Trello. We preserve the original filename and file type. Trello has a per-board attachment limit (10 MB on Free, 250 MB on Standard and Premium); we verify total attachment volume against the destination plan during scoping and flag any attachments that exceed the limit. File-size-over-limit items are noted in the migration inventory for the customer to address manually.

ONES.com

Automation Rule

maps to

Trello

Butler rule (must be rebuilt)

1:1
Fully supported

Automation rules in ONES Project (task status change triggers, assignee notifications, field updates) are not exposed via a migration endpoint and cannot be exported. We identify all active automation rules during discovery and deliver a written automation inventory listing each rule's trigger, conditions, and actions with a recommended Trello Butler equivalent. The customer's admin rebuilds these in Butler post-migration. We do not migrate automation logic as code.

ONES.com

Pipeline Configuration

maps to

Trello

CI/CD rebuild required

1:1
Fully supported

CI/CD pipeline definitions in ONES Build and ONES Pipeline are tightly coupled to the ONES execution environment and connected repositories. These configurations do not port across platforms and must be rebuilt in the destination CI/CD system (GitHub Actions, GitLab CI, Jenkins, or similar). We migrate the ONES Build and TestCase records as data but flag that pipeline definitions require a separate CI/CD rebuild project post-migration.

Pair-specific challenges

  • Automation rules have no export or migration path

    ONES Project automation rules (triggers based on task status changes, assignees, or field values, and resulting notification or update actions) are not exposed via any documented migration endpoint. We identify every active automation rule during discovery and deliver a written inventory with each rule's trigger, conditions, actions, and a recommended Trello Butler equivalent. The customer's admin rebuilds these in Butler post-migration. Migrations that skip this step leave Trello boards with no automated card movements, due-date reminders, or status-based actions, which disrupts established team workflows on day one.

  • Archived Cards may not export from Trello without explicit restoration

    Trello's standard export does not include archived cards by default. Community reports confirm that organizations migrating from Trello to other platforms discover that archived cards must be manually unarchived before export to be included. Since ONES tracks closed Tasks and Bugs with a Done status (not a separate archive), this gotcha is directional: any customer who previously used Trello as a staging area with heavy archival may have Tasks in ONES that originated from archived Trello cards. We validate archived card count during discovery and flag this as a pre-migration step for the customer to review.

  • Trello Custom Fields Power-Up requires a paid plan

    Custom fields in Trello are not a core feature; they require the Standard ($5/user/month) or Premium ($10/user/month) plan via the Custom Fields Power-Up. ONES custom fields on Tasks, Bugs, and TestCases migrate as custom field data only if the destination Trello workspace has the appropriate plan. We verify the workspace plan during scoping. If the destination is on Trello Free, custom field data migrates as plain text in the Card description with field names noted. We flag this limitation in the migration scope before work begins so the customer can upgrade or accept text-only custom fields.

  • ONES Wiki PDF export silently truncates wide tables

    When exporting ONES Wiki pages as PDF, tables exceeding approximately 720px width are scaled down and may be truncated if they still exceed the page width. This means rich-table documentation can lose data silently on export. We flag wide-table pages during the migration audit and recommend exporting those pages as Word (.docx) files instead, which preserves full table content. We verify table widths before committing the Wiki migration plan and document any pages requiring the .docx approach.

  • Trello API returns empty values for some custom field reads

    Trello's API has a documented behavior where the Get Custom Field module returns empty values for the Value field of certain customFieldId records. Community reports confirm this affects dropdown list and reference custom fields specifically. We handle this by validating custom field values post-import against the source ONES data during reconciliation. Any Card with a missing or empty custom field value is flagged in the reconciliation report for manual review rather than silently accepting an empty field. This adds a verification pass to the migration timeline but prevents data-integrity surprises after cutover.

Migration approach

Six steps for a successful ONES.com to Trello data migration

  1. Discovery and data audit

    We audit the source ONES account across all products in scope (ONES Project, ONES Wiki, ONES TestCase). We extract the full object inventory: Project list, Task counts and hierarchy depth, Bug counts by severity, Requirement counts, Sprint history, TestCase volume, User and member list, active automation rules, and attachment volume. We also extract any ONES on-premises export configuration if applicable. The discovery output is a written migration scope document with record counts, object dependency graph, and a Trello workspace plan verification (Free, Standard, or Premium) to confirm custom field support before migration design begins.

  2. Trello workspace and board structure design

    We design the destination Trello workspace structure based on the ONES Project inventory. Each ONES Project becomes either a standalone Board or is consolidated with other projects into a single board per team, depending on the customer's preference during scoping. We define the List structure per board (typically To Do, In Progress, Review, Done), label sets (Bug severity, priority, Requirements), and custom field schemas for Standard or Premium plans. We also map Sprint representation strategy (due dates with Labels, or List-per-Sprint) and document the decision for customer sign-off before extraction begins.

  3. Test migration to a staging workspace

    We run a full migration into a Trello staging workspace using a representative subset of ONES data (one active project, 50-100 cards, 5-10 Bugs, 2-3 Requirements, 5-10 TestCases, 1-2 Wiki pages). The customer reconciles card counts, verifies checklist subtask hierarchy, confirms due date mapping, reviews label application, and spot-checks 10-20 random Cards against the source ONES records. Any mapping corrections, label naming changes, or List structure adjustments happen in this phase before production extraction. We do not begin production extraction until the staging sign-off is received.

  4. User and member reconciliation

    We extract every distinct email address referenced on ONES Tasks, Bugs, Requirements, TestCases, and Wiki page authors, and match against Trello workspace members. Any email with no matching Trello member goes to a reconciliation queue for the customer's admin to provision before record import. Trello does not support inactive member records, so any ONES user who has left the team must be handled as a 'deactivated' note on the Card rather than a Trello member assignment. We provide a user mapping spreadsheet as part of the reconciliation step.

  5. Production migration in dependency order

    We run production migration in this order: Members (manual provisioning validated), Boards (created with description and settings), Cards (Tasks, Bugs, Requirements, TestCases mapped per the design document), Checklists (subtasks on each Card), Custom fields (on Standard or Premium plans), Attachments (downloaded from ONES and re-uploaded to Cards), Wiki pages (.docx export attached to the relevant Card or standalone Card), and Sprint dates (applied as due dates and Labels per the Sprint mapping strategy). Each phase emits a row-count reconciliation report. We use Trello's REST API with rate-limit handling and exponential backoff for bulk operations. Any Cards with unresolved parent-record lookups are held in a retry queue rather than imported with broken references.

  6. Cutover, validation, and automation rebuild handoff

    We freeze writes in ONES during cutover, run a final delta pass for any records modified during the migration window, then enable Trello as the system of record. We deliver the automation inventory document (with Butler rebuild recommendations), the pipeline rebuild note (for ONES Build and Pipeline), and the final reconciliation report showing record counts across all object types. We support a one-week hypercare window for reconciliation issues raised by the team. We do not rebuild ONES automation rules as Butler rules inside the migration scope; that work is documented separately for the customer's admin to complete as a post-migration task.

Most ONES.com to Trello migrations land between four and six weeks for accounts with up to 20,000 Cards (Tasks, Bugs, Requirements combined) across fewer than 20 boards. Migrations with active Wiki page content, TestCase libraries, large attachment sets, or Sprint-date preservation requirements move to six to ten weeks because of wiki table handling, checklist conversion, and custom field type translation work. The timeline assumes a two-week discovery and scoping phase, one-week staging migration and sign-off, and a two-to-four-week production migration depending on data volume.
