Overview
Moving from Workzone to Trello is a structural flattening. Workzone organizes work in a Workspaces > Projects > Tasks > Subtasks hierarchy with optional custom fields, approval workflows, time tracking, and intake forms. Trello operates on Workspaces > Boards > Lists > Cards with checklist items replacing true subtasks and Custom Fields, Calendar, and other advanced features gated behind Power-Ups on paid plans. We extract Workzone data through its native export pathways, map the project hierarchy to Trello boards, carry forward task descriptions and assignees, and batch-move attachments to avoid the memory exhaustion issues documented in community migration threads. Approval records, time entries, and expense data do not have native Trello equivalents; we document these as gaps in the delivered field map and discuss Power-Up alternatives if the customer requires them post-migration.
Every standard and custom field arrives verified.

Object mapping
Each row shows how a Workzone 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.
Workzone
Workspace
Trello
Workspace
1:1Workzone Workspaces map directly to Trello Workspaces as top-level organizational containers. We preserve the workspace name, member list, and any workspace-level settings available through Workzone's export. Trello Enterprise workspaces support additional administrative controls that we configure post-migration if the customer's destination is an Enterprise workspace.
Workzone
Project
Trello
Board
1:1Workzone Projects map to Trello Boards with project name becoming board name and project description populating the board description field. Project-level members transfer as board members with the same permission level (admin, member, observer). Archived projects in Workzone map to archived boards in Trello, though Atlassian community threads document that archived cards do not appear in standard Trello exports and must be restored to boards before export or handled as a manual step.
Workzone
Task
Trello
Card
1:1Workzone Tasks map to Trello Cards with task title becoming card name, task description mapped to card description, due date transferred to the due date field, and priority mapped to Trello label colors if the customer defines a label schema during scoping. Assignees transfer as card members. Tasks with dependencies in Workzone have no direct Trello equivalent; we document the dependency pair in the delivered field map and the customer recreates dependencies manually or uses the Dependencies Power-Up.
Workzone
Subtask
Trello
Checklist item
1:manyWorkzone Subtasks nest inside parent tasks and map to Trello checklist items on the corresponding card. The subtask hierarchy flattens into a single checklist per card because Trello does not support nested checklist items. Subtask assignees do not transfer to individual checklist items; the parent card retains the full assignee set. If the customer requires subtask-level assignee tracking in Trello, we recommend converting subtasks to child cards using the Card repeater or Butler automation post-migration.
Workzone
Custom Fields (paid add-on)
Trello
Custom Fields (Power-Up)
lossyWorkzone custom field definitions and values map to Trello's Custom Fields Power-Up. We first verify during scoping that the Workzone plan includes the custom field add-on; Starter plans without this add-on have no custom field data to migrate. Field types including text, number, date, and choice lists map to their Trello equivalents. Multi-select choice lists in Workzone map to Trello multi-select custom fields. The Custom Fields Power-Up requires a Standard or higher Trello plan.
Workzone
Attachment
Trello
Card Attachment
1:1Files attached to Workzone tasks and projects are downloaded from Workzone storage and re-uploaded as Trello card attachments. Community migration threads document memory exhaustion issues when bulk attachment downloads run without chunking; we batch download in groups of 50 files with exponential backoff on any timeout. File names, upload timestamps, and uploader identity are preserved as attachment metadata. Trello enforces a 10MB attachment limit on free plans and 250MB on Standard and above.
Workzone
Comment
Trello
Card Comment
1:1Workzone task-level comments and threaded replies map to Trello card comments with author, timestamp, and content preserved. Mentions and @-references from Workzone are mapped to Trello @mention syntax in plain text. Emoji reactions do not transfer; we flag these in the delivered comment inventory as requiring manual recreation if the customer values reaction history.
Workzone
Intake Form
Trello
Custom Fields (Power-Up) or Board Description
lossyWorkzone intake forms auto-populate project fields on creation. The submitted form data maps to a combination of custom fields on the board (if the Custom Fields Power-Up is active) and the board description field for narrative intake context. Conditional logic in Workzone intake forms does not migrate; we document the form structure in the delivered automation inventory for the customer's admin to rebuild in Trello Butler or a third-party form tool like Google Forms.
Workzone
Approval Record (Team/Enterprise)
Trello
Card Label or Checklist
1:1Document approvals in Workzone (Team and Enterprise tier) include approver identity, status, timestamps, and markup history. Trello has no native approval workflow object. We map approval status to a labeled column (Approved/Rejected/Pending) or a checklist item on the card, preserving the final status and approver name. Full markup history (redlines, annotations) does not migrate; we flag the proofing history gap in the delivered field map and recommend the customer's admin review proofed documents directly in Workzone before cutover.
Workzone
Time Entry (Team/Enterprise)
Trello
Card label or External Time Tracking Power-Up
1:1Workzone time entries on Team and Enterprise plans map to Trello card labels with the logged hours encoded (for example, a label named '4.5h' or a date-labeled label). For migrations where time tracking is business-critical, we recommend installing a time tracking Power-Up (Toggl Track, TimeCamp, or similar) post-migration and mapping Workzone time entry data into the Power-Up's records as a parallel step. We do not build custom time-tracking integrations as part of standard migration scope.
Workzone
Project Template
Trello
Board Template
1:1Workzone project templates (available on Team and Enterprise) including task scaffolding, default assignees, and default dates map to Trello board templates. We export the template structure as a template board in Trello during migration. The customer configures template boards under Trello's Board Templates from Settings. Template creation from migrated boards is a post-migration step the customer's admin handles using Trello's 'Make template' action.
Workzone
Tag
Trello
Label
1:1Workzone tags on tasks and projects map to Trello board labels. We preserve tag names as label names and assign label colors if the source data includes color metadata. Multi-value tag arrays on a single Workzone task map to multiple Trello labels on the corresponding card. Label management in Trello is per-board, so we recommend the customer's admin standardize a label schema across boards post-migration.
Workzone
User (Full Seat)
Trello
Workspace Member
1:1Workzone full-seat users (creators, project managers) map to Trello workspace members. We resolve by email match where possible. Collaborator-level users (reviewers, guests) without full Workzone seats map to Trello board observers or members depending on the access level required. Trello Free plans limit workspace members to one board per workspace; Standard or Business Class is required for unlimited boards and full workspace collaboration.
Workzone
Expense Record (Enterprise)
Trello
Not migrated (no equivalent)
1:1Workzone Enterprise expense records with vendor, amount, and date map to an external expense tracking system post-migration. Trello has no native expense object. We export expense records as a CSV alongside the migration and flag the gap in the field map. The customer configures a replacement expense workflow in their accounting or PSA tool, or implements a Trello-compatible form-based solution.

Gotchas + challenges
Platform-specific issues from each side, plus the pair-specific challenges that don't show up on either platform's page on its own.
Workzone gotchas
Custom fields are a paid add-on, not standard on all plans
Starter plan enforces hard workspace and storage limits
Time tracking and expense features are tier-gated
No documented public API for programmatic migration
Trello gotchas
Billing model uses maximum seat quantity at term midpoint
Custom Field data historically stored in pluginData
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
Export scoping and Workzone data audit
We audit the Workzone account across plan tier, workspace count, project count, task hierarchy depth, subtask volume, attachment count and total file size, custom field definitions (if the add-on is active), intake form structure, approval record existence, and time entry data. We also identify any archived workspaces or projects that may be excluded from standard export. The audit output is a written data inventory identifying every object that will migrate, every object that requires an alternative mapping, and any gaps that require manual handling or external tooling.
Destination Trello workspace and plan configuration
We verify the destination Trello workspace plan tier and configure required Power-Ups including Custom Fields, if the customer's data requires it. We set up board templates in Trello from exported Workzone project templates, define label color schemas mapped from Workzone tags, and create any required board automation (Butler rules) that can be configured from template data. If the destination workspace is on a free plan, we document the Power-Up upgrade path before proceeding.
Export scaffolding and data extraction
Because Workzone has no public API, we work with Workzone's native export output or construct a manual extraction scaffold for the customer's data. We extract workspaces, projects, tasks, subtasks, comments, attachments, user and collaborator lists, custom field definitions and values, intake form data, and approval records. Any archived records are explicitly requested for inclusion. Attachments are downloaded in batched chunks of 50 to avoid memory exhaustion documented in community migration threads.
Attachment re-upload and board creation
We create Trello boards from Workzone projects in dependency order (workspace first, then boards, then lists, then cards). Attachments are uploaded to each card via Trello's card attachment API with upload confirmation logged per card. File upload failures trigger retry with exponential backoff and are logged in the reconciliation report. For attachments exceeding Trello free-plan limits, we either upload to a linked Google Drive or SharePoint location and add a card link, or the customer upgrades to a paid Trello plan.
Record migration with hierarchy preservation and reconciliation
We migrate records in dependency order: workspace members first, then boards, then lists, then cards, then checklist items. Subtasks are converted to checklist items with parent card membership resolved. Custom field values populate via the Custom Fields Power-Up API on boards where the Power-Up is active. Approval status maps to labels or checklist items. We reconcile record counts against the source data inventory for every phase and escalate any discrepancy exceeding 2% before proceeding.
Cutover, delta sync, and rebuild handoff
We freeze Workzone writes during the cutover window, run a delta migration of any records modified during the migration window, and confirm the final record count against source. We deliver the migration summary including record counts per object, unmapped objects, and attachment failure log. We deliver the intake form structure and approval workflow inventory as a written document for the customer's admin to rebuild in Trello Butler or a third-party form tool. We support a one-week post-cutover window for reconciliation issues raised by the customer's team.
