Overview
Moving from CONTACT Project Office to Trello is a structural restatement, not a straight record copy. CONTACT Project Office organizes work as Projects containing Tasks and Subtasks in a hierarchical parent-child tree; Trello organizes work as Boards containing Lists containing Cards with optional checklists inside each Card. We resolve that structural difference during scoping by mapping each CONTACT Task to a Trello Card and each CONTACT Subtask to a checklist item within that Card, preserving the owner, due date, and custom field values at the right nesting level. We support all four CONTACT Project Office task statuses (open, in progress, completed, on hold) into Trello list positions that reflect the customer's workflow. Attachments migrate as card attachments with the original filename and uploader metadata preserved. We do not migrate Automations or Workflow configurations; we deliver a written inventory of each for the customer to rebuild in Trello Butler or a Power-Up.
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 CONTACT Project Office 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.
CONTACT Project Office
Project
Trello
Board
1:1Each CONTACT Project Office Project maps to one Trello Board. We preserve the Project name as the Board name and the Project description as the Board description (imported as a card or stored in the Board settings). If the CONTACT Project has multiple task lists or status categories, we map these to Trello Lists within the Board. Project-level custom fields are applied to every Card within the Board as Trello card-level custom fields, configured once and inherited per Card.
CONTACT Project Office
Task
Trello
Card
1:1CONTACT Tasks map directly to Trello Cards. The Task name becomes the Card title, the Task description becomes the Card description (Markdown-formatted), and the Task status maps to one of the target Board's Lists. If the customer uses a Kanban-style list in CONTACT with open/in-progress/completed/on-hold columns, these map to Trello Lists by status. We preserve the original Task creation date as a Card custom field or as the Card creation timestamp.
CONTACT Project Office
Subtask
Trello
Checklist Item
1:1CONTACT Subtasks map to Trello checklist items within the parent Card. The Subtask name becomes the checklist item text, and Subtask completion status maps to checked/unchecked on the checklist item. We resolve the parent Task-to-Card relationship during extraction so each checklist item lands under the correct Card. Subtask assignees are noted as Card members or as a custom field on the checklist item if the Power-Up supports it.
CONTACT Project Office
Assignee (Task-level)
Trello
Card Member
1:1CONTACT Task assignees (members assigned to a specific Task) map to Trello Card members. We resolve assignees by email match against the target Trello workspace membership. Any assignee without a matching Trello user goes to a reconciliation queue for the customer's admin to provision before Card assignment migration. Project-level assignees are mapped to Board membership separately.
CONTACT Project Office
Custom Field (Task-level)
Trello
Card Custom Field
lossyCONTACT Task custom fields (text, number, date, dropdown, checkbox) map to Trello card custom fields. We configure the custom field in the target Board before migration using Trello's custom field types (text, number, date, dropdown, checkbox, rating). The mapping is applied at the Card level, so each Card receives its source Task's custom field values. Custom fields on Subtasks are stored as checklist item labels or as Card-level custom fields with a subtask prefix notation.
CONTACT Project Office
Attachment
Trello
Card Attachment
1:1CONTACT Task and Subtask attachments migrate as Card attachments in Trello. We preserve the original filename, file size, and uploader metadata. Attachments are uploaded directly to Trello's attachment storage (subject to Trello's per-file size limits: 10 MB on Free, 250 MB on Premium and Enterprise). Large files from CONTACT self-hosted instances are chunked if needed and re-assembled at the destination. Image attachments become Cover images on Cards if the customer requests this during scoping.
CONTACT Project Office
Comment
Trello
Card Comment
1:1CONTACT Task and Subtask comments map to Trello Card comments. The comment body migrates as plain text or Markdown-formatted text. We preserve the original commenter name and timestamp. If the source CONTACT instance stores internal notes separately from public comments, internal notes migrate as Card comments with an [Internal] prefix so the customer can identify them post-migration.
CONTACT Project Office
Task Status
Trello
List
lossyCONTACT Project Office task statuses (open, in progress, completed, on hold, or custom statuses) map to Trello Lists. We define the List names during scoping based on the customer's current status labels and the target Kanban workflow. If the customer wants a four-list Kanban (To Do, In Progress, Review, Done), we map the CONTACT statuses to those lists during extraction before Card creation. Custom status values are preserved as Card labels if the customer prefers label-based categorization over list-based.
CONTACT Project Office
Task Priority
Trello
Card Label
lossyCONTACT Task Priority (if used as a custom field or native property) maps to Trello Card Labels. We define the label colors and names during scoping to match the CONTACT priority scheme (e.g., Critical = red label, High = orange, Medium = yellow, Low = green). Priority values stored in custom fields map to custom field drop-down values instead of labels at the customer's preference.
CONTACT Project Office
Task Due Date
Trello
Card Due Date
1:1CONTACT Task due dates migrate to Trello Card due dates directly. If a Subtask has its own due date, we store it as a checklist item label with the date or as a note on the checklist item. Completed date from CONTACT Task maps to the Card's due date completion status.
CONTACT Project Office
Project Timeline (Start/End)
Trello
Board Calendar Power-Up or Card Dates
lossyCONTACT Project Office project start and end dates have no direct Trello Board equivalent. We migrate project-level dates as Card custom fields on all Cards in the Board, or we configure the Trello Calendar Power-Up with the Card due dates to visualize the project timeline. If the customer uses milestone tasks (tasks with zero duration), we create milestone Cards marked with a label.
CONTACT Project Office
Automation / Workflow Rule
Trello
Written inventory only (no code migration)
lossyCONTACT Project Office workflow rules (automated actions triggered by task status changes, assignments, or date triggers) have no direct Trello Butler equivalent. We audit every active workflow rule, document its trigger, conditions, and actions in a written handoff inventory, and recommend a Butler rule or Automation Power-Up configuration for each. The customer's admin rebuilds the automations in Trello post-migration.

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.
CONTACT Project Office gotchas
Public documentation is limited; API surface is gated to customers
Project structure is template-driven and may include CIM Database links
Hybrid agile + classical tasks coexist in the same project
Ratings and peer feedback are sparse — discovery has to be customer-led
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
Data discovery and export scoping
We audit the source CONTACT Project Office instance to inventory Projects, Tasks, Subtasks, custom fields (per task and per project), attachments (count, total size, largest file), comments, assignees, and workflow rules. We determine the export method: native CONTACT export if available, database query for self-hosted instances, or manual CSV extraction guided by FlitStack AI for edge cases. We deliver a written discovery summary with record counts, custom field inventory, attachment size audit, and a recommendation for the Trello plan tier based on custom field requirements and attachment sizes.
Schema design and board structure mapping
We design the Trello workspace and board structure based on the CONTACT project inventory. This includes creating one Board per Project, defining Lists per task status or workflow stage, configuring custom fields per Board (using native custom fields on Standard and above, or the Amazing Fields Power-Up on Free), and defining Card labels for priority or category if those are used in CONTACT. We map CONTACT subtask hierarchy to checklist items and resolve any subtask-level metadata (due dates, assignees) that needs to be flattened. The board structure is validated in a test workspace before production migration begins.
Sandbox migration and reconciliation
We run a full migration into a test Trello workspace using production-like data volume. The customer reviews the migrated boards, verifies checklist item nesting, confirms custom field values on Cards, checks attachment accessibility, and spot-checks 20-30 Cards against the CONTACT source. We resolve any mapping corrections (wrong list, missing checklist item, custom field type mismatch) before production migration begins. This step typically takes three to five business days.
Member reconciliation and workspace provisioning
We extract every distinct assignee from CONTACT Tasks and Subtasks and match them by email against the target Trello workspace membership. Assignees without a matching Trello user go to a reconciliation queue. The customer provisions any missing workspace members and confirms their access level (Admin, Member, or Observer per Board). Migration cannot proceed past Board creation until member provisioning is confirmed because Card member assignment depends on existing Trello users.
Production migration in dependency order
We run production migration in phases: workspace and Boards created first, then Lists configured per Board, then Cards with descriptions and checklist items (Subtasks resolved by parent Task), then custom fields populated per Card, then attachments uploaded per Card, then comments added per Card, then Card members assigned, then labels applied. Each phase emits a row-count reconciliation report before the next phase begins. Delta migration captures any CONTACT records modified during the migration window before cutover.
Cutover, validation, and automation handoff
We freeze CONTACT Project Office write access during cutover, run a final delta migration of records modified during the window, validate Card counts and attachment integrity in Trello, then enable Trello as the system of record. We deliver the workflow rule inventory document to the customer's admin team for Butler or Automation Power-Up rebuild. We support a three-business-day hypercare window where we resolve any reconciliation issues. We do not rebuild CONTACT workflow rules as Butler rules inside the migration scope; that is a separate engagement or an internal admin task.
