Overview
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.
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 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
Trello
Board
1:1ONES 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
Trello
Card
1:1ONES 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
Trello
Card (with Label)
1:1ONES 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
Trello
Due date range + List or Label
lossyONES 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
Trello
Card (with Requirements Label)
lossyONES 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
Trello
Card (with checklist steps)
lossyONES 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
Trello
Card attachment or external link
lossyONES 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
Trello
Member
1:1Project 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
Trello
Power-Up Custom Field
lossyONES 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
Trello
Card attachment
1:1Attachments 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
Trello
Butler rule (must be rebuilt)
1:1Automation 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
Trello
CI/CD rebuild required
1:1CI/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
Migration approach
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.
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.
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.
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.
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.
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.
