Overview
Moving from Trello to monday.com is a structural upgrade from a flat Kanban board model to a multi-view Work OS. Trello's Board → List → Card hierarchy maps to monday.com's Board → Group → Item structure, with each Trello list becoming a monday.com group within a board. We preserve card titles, descriptions, due dates, start dates (from Trello Premium Power-Ups), Labels, and Custom Field values across all supported field types. monday.com's native Trello importer supports only Task Name, Labels, and Dates, dropping Descriptions, Checklists, Activities, and Files — we bypass it entirely and use direct API extraction from Trello followed by monday.com API insertion to maintain full fidelity. Butler automation rules, Power-Up configurations, and Calendar/Timeline/Dashboard view settings do not migrate; we document them in a written handoff for the customer's admin to rebuild using monday.com's automation center.
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 Trello object lands in monday Work Management, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Trello
Board
monday Work Management
Board
1:1Each Trello Board maps to a monday.com Board. We extract board name, description, visibility (public/private), organization membership, and background color during discovery. monday.com boards require a board type selection (Main, Shareable, or Private) at creation; we default to Shareable and the customer's admin adjusts permissions post-migration. Board-level settings (voting, self-assignment, card covers) are documented and configured in monday.com by the admin.
Trello
List
monday Work Management
Group
1:1Trello Lists map to monday.com Groups within a board. We preserve list order and list name, using the list name as the group title. Archived lists in Trello become archived groups in monday.com. List-level power-ups (such as list limits) do not have a monday.com equivalent and are documented for manual reconfiguration.
Trello
Card
monday Work Management
Item
1:1Trello Cards map to monday.com Items within a Group. We migrate card title, description (with Markdown rendered to monday.com's rich text format), due dates, start dates (from Power-Up fields on Premium boards), cover colors, and position within the group via item ordering. Card URL is preserved in a monday.com text column for traceability back to the source. Archived cards migrate as archived items.
Trello
Custom Field
monday Work Management
Column (various types)
lossyTrello Custom Fields map to monday.com columns by type: text fields to Text columns, numbers to Numbers, dates to Date columns, checkboxes to Checkboxes, dropdowns to Dropdown columns, and Rating Power-Up fields to a numeric or stars column type. We detect whether Custom Field data originates from the core API or legacy pluginData during discovery. Legacy pluginData Custom Fields require a manual audit post-migration to confirm field values were extracted correctly.
Trello
Label
monday Work Management
Tag or Label Column
lossyTrello Labels (color-coded tags per board) map to monday.com Tags or a Label column depending on the destination board configuration. We preserve label name and color on the migrated item. Label sets that are heavily relied upon for filtering in Trello should be converted to monday.com Status columns (a dedicated Status column per label category) for better automation and reporting support.
Trello
Checklist
monday Work Management
Subitems
1:manyTrello card checklists migrate as monday.com Subitems attached to the parent item. Each checklist within a card becomes a subitem group; individual checklist items become subitems with their own completion state. monday.com's subitem model supports assignees, due dates, and notes per subitem, providing richer tracking than Trello's flat checklist. Cards with multiple checklists produce multiple subitem groups in the same parent item.
Trello
Attachment
monday Work Management
File Column or Integration
1:1Trello stores file attachments on Amazon S3 with per-plan size limits (10MB Free, 250MB Enterprise). We download all raw attachments at migration time and upload to monday.com's file storage. monday.com Basic includes 5 GB of storage; Standard includes unlimited storage. Board-level attachments (linked rather than card-attached) migrate as a file column on the board. Attachment links are re-hosted on monday.com S3 with the original filename preserved.
Trello
Member (assignee)
monday Work Management
Assignee Column
1:1Trello board members assigned to cards map to monday.com Assignee columns. We match assignees by email address against monday.com workspace users. Guests in Trello who are assigned to cards but may not consume a paid seat are migrated as monday.com workspace members with the appropriate role assigned by the admin post-migration. Unmatched assignees are flagged in the reconciliation report.
Trello
Workspace
monday Work Management
Workspace
1:1A Trello Workspace maps to a monday.com Workspace. We preserve workspace name and map board groupings within the workspace to monday.com folder or board structure. Multi-workspace Trello configurations map to multiple monday.com workspaces, or a single monday.com workspace with separate boards, depending on the customer's preference during scoping.
Trello
Workspace Membership
monday Work Management
Workspace Members
1:1Trello workspace members are invited to the monday.com workspace with the equivalent role. Trello's 6 user roles map to monday.com's 5 permission levels (Owner, Admin, Member, Editor, Viewer). Guest roles in Trello that consume a seat migrate to monday.com Member or Viewer roles as appropriate.
Trello
Card Activity (comments)
monday Work Management
Updates
1:1Trello card comments migrate as monday.com Updates on the item. We preserve comment text, author (mapped by email to monday.com user), and timestamp. Comment attachments migrate as file attachments on the item. Activity history (card move events, edit history, due date changes) is not migrated as it is a chronological log rather than a current-state field.
Trello
Butler Automation
monday Work Management
Automation (documented, not migrated)
1:1Butler automation rules do not migrate to monday.com automations because they are different automation models with different triggers, conditions, and actions. We deliver a written inventory of every active Butler rule including trigger type, conditions, and actions with a recommended monday.com Automation Center equivalent. The customer's admin rebuilds them post-migration. Butler run history is not preserved.
Trello
Power-Up Data
monday Work Management
N/A
1:1Power-Up data (Calendar, Timeline, Dashboard, custom third-party Power-Ups) stores data in its own schema inaccessible via Trello's standard API. Calendar and Timeline are display-layer views of card data that migrates normally. Dashboard aggregation settings do not migrate; we document the dashboard configuration as-is and recommend rebuilding it as a monday.com dashboard. Third-party Power-Up data (time tracking, custom fields, forms) is inventoried for manual assessment.

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.
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
monday Work Management gotchas
Subitems have no bulk export endpoint
API complexity budget constrains query depth
Daily call limits vary sharply across plan tiers
Automation and integration rules do not export via API
Saved views are not exposed via API
Pair-specific challenges
Migration approach
Discovery and scope definition
We scan the Trello workspace via the REST API to extract all boards, lists, cards, Custom Fields (detecting pluginData vs core API storage), Labels, members, workspace settings, and Butler automation rules. We identify card count, checklist volume per card, attachment count and cumulative size, and any Power-Up data (Calendar, Timeline, Dashboard) that will not migrate via standard API. The discovery output is a written migration scope with board-to-board mapping, Custom Field type inventory, and the Butler automation rule list requiring rebuild.
Schema design and monday.com workspace preparation
We design the monday.com destination schema: one Board per Trello board, Groups per List, Items per Card, and Column types matched to every Custom Field. We configure Label conversions (tag vs Status column) based on how the customer uses Labels for filtering and automation. We set up workspace membership with roles mapped from Trello workspace permissions. Board visibility (public/private) from Trello maps to monday.com board sharing settings.
Discovery scan for legacy Custom Field storage
During extraction we detect whether Custom Fields on each board use the core Custom Fields API or legacy pluginData. For boards with pluginData Custom Fields, we apply the legacy extraction method and flag the affected fields in the reconciliation report. The customer audits a sample of these fields post-migration to confirm value accuracy before decommissioning the source Trello workspace.
Subitem conversion and checklist resolution
We convert each Trello checklist (within each card) to a monday.com subitem group. Named checklists within a card become subitem groups; individual checklist items become subitems with their own completion state. We flag cards with more than 50 checklist items across all checklists for customer review — these can alternatively be converted to a text column with a checklist-formatted block to avoid subitem bloat.
Attachment extraction and re-upload
We download all file attachments from Trello's S3 storage at migration time, preserving original filenames and metadata. Files are uploaded to monday.com's storage with a file column added to each item carrying an attachment. We validate upload success and flag any files exceeding monday.com's per-plan size limit (5 GB Basic, unlimited Standard and above) for manual handling. Card comments with embedded attachments are processed as a combined item update with file attachment.
Production migration and reconciliation
We run the full migration in record-dependency order: Workspace and members first, then boards, groups, items with all columns and subitems, attachments, and finally updates (comments). Each phase emits a row-count reconciliation report. We verify checklist completion states, Custom Field values, due dates, and assignee mappings against a random sample of source records before sign-off.
Cutover, Butler inventory delivery, and admin handoff
We freeze Trello writes during cutover, run a delta pass for records modified during the migration window, then hand off monday.com as the system of record. We deliver the Butler automation inventory document to the customer's admin with recommended monday.com Automation Center equivalents and trigger mappings. We do not rebuild Butler automations as monday.com automations inside the migration scope. We support a 48-hour post-cutover window for reconciliation issues before closing the engagement.
