Overview
Moving from Kantree to Trello is a structural simplification, not a lateral move. Kantree's workspace-centric data model with 27 custom field types, 7 view types, KQL-powered automations, and unlimited subcard nesting has no equivalent in Trello, which uses 9 fixed card fields, a single board view on the free tier, and trigger-action Butler rules. We begin by auditing the full Kantree field schema and card-type inheritance tree, then flag every custom field that requires a Power-Up or manual workaround at the destination. We export card relationships as embedded checklist references or card-description links since Trello has no native many-to-many card linking. We deliver a written automation inventory for every KQL rule so the customer's admin can rebuild in Butler or a Power-Up. Formula fields are exported as static values at migration time, and the customer chooses whether to store them as static text or recreate them via a third-party Power-Up. Workspace and project hierarchy map to Trello boards and lists, with the understanding that Trello's board model does not support the nested project structure that Kantree provides natively.

Object mapping
Each row shows how a Kantree 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.
Kantree
Workspace
Trello
Workspace or Board
lossyKantree workspaces map to Trello Workspaces (Free tier: 1 Workspace; Standard and above: multiple Workspaces). Each Kantree workspace becomes a Trello Workspace, and the customer chooses whether to create one master Trello Workspace or multiple Trello Workspaces matching the Kantree structure. Workspace color themes and display settings have no Trello equivalent and are documented as manual configuration steps post-migration.
Kantree
Project
Trello
Board
1:1Kantree projects map to Trello boards, preserving project name, description, card group (column) structure as board lists, and any project-level custom fields as card-level fields. The project creation date migrates as a card description annotation. If the Kantree project has multiple card types, we create separate boards per card type or use Trello labels as a card-type proxy, depending on scoping preference.
Kantree
Card
Trello
Card
1:1Kantree cards map directly to Trello cards with the title, description, due date, assignee, cover image, and checklist content preserved. Trello card descriptions accept Markdown, so rich text from Kantree migrates with formatting converted. The card creation timestamp and last-modified timestamp migrate as custom fields (Start Date or due date metadata) since Trello cards do not carry creation-date metadata by default.
Kantree
Card Type
Trello
Label
lossyKantree card types (Bug, Feature, Invoice, Patient, etc.) do not have a direct Trello equivalent. We map card types to Trello labels using a naming convention (card_type:Bug, card_type:Feature). For workspaces with fewer than 10 card types, this covers all cases within Trello's label limit. For workspaces with more than 10 card types, we flag the limitation and recommend splitting by board or using a Power-Up like Custom Fields to carry the type as a structured attribute.
Kantree
Custom Field
Trello
Power-Up Custom Fields or Card Description
1:1Kantree supports 27 custom field types. The migration strategy is tiered by field type: text, number, date, single-select, and multi-select map to Trello Standard/Power-Up Custom Fields. Rating fields map to a label with N stars. Formula fields are exported as static text with the last computed value. Card reference fields are exported as checklist items with card links. User reference fields map to Trello members. Fields that cannot map (such as Kanban swim lane assignments or KQL-conditional visibility flags) are documented as manual configuration steps post-migration.
Kantree
Subcard
Trello
Checklist Item
lossyKantree subcards are independent cards with their own card types, fields, assignees, and subcards (recursive nesting). Trello checklists have no custom fields, no assignees, and no nested checklists. We flatten subcard hierarchies to checklist items, embedding the subcard title and, optionally, the last-known field values as text in the checklist item name. If the subcard depth exceeds two levels, we recommend breaking the chain into separate boards post-migration using a Trello Power-Up for board linking.
Kantree
Card Relationship
Trello
Card Description or Checklist
1:1Kantree supports one-to-one, one-to-many, and many-to-many card relationships defined at workspace level. Trello has no native card-linking or many-to-many relationship fields. For each relationship type, we embed a structured reference in the child card's description using a markdown link format (Parent: [[Card Name]]), or we create a 'Related Cards' checklist with the linked card names as checklist items. The relationship type label (blocks, implements, relates_to) is preserved as a label prefix on the link reference.
Kantree
Card Group (Column)
Trello
List
1:1Kantree card groups (columns) within a project map directly to Trello lists on the corresponding board. Card group color coding, card ordering within groups, and group-level WIP limits migrate as Trello list settings and color labels. Kantree's card limit indicators (highlighted in red with icon) have no Trello equivalent and are documented as a manual board configuration note.
Kantree
Comment
Trello
Card Activity Comment
1:1Kantree comments with author, timestamp, and text body map to Trello card comments. The 2-hour editable window for authors does not exist in Trello (comments are permanently editable by any board member), so we migrate the comment text and author but do not preserve the edit-window constraint. Rich text in comments migrates with markdown conversion. Comments with @mentions carry the mention as plain text in Trello since Trello comment @mentions resolve differently.
Kantree
Attachment
Trello
Card Attachment
1:1Kantree file attachments (drag-and-drop or image toolbar upload) migrate to Trello card attachments. We export the file metadata (name, size, upload date, uploader) and download the file from Kantree's storage layer, then re-upload to Trello. Files are attached to the migrated card at the same position in the attachment list. If a file exceeds Trello's 10MB attachment limit (Free and Standard), we flag the file and the customer chooses whether to attach via a Trello Power-Up (such as Google Drive or Dropbox integration) instead.
Kantree
User / Member
Trello
Member
1:1Kantree organization members (billable) map to Trello board members. Project observers (free but read-only) map to Trello observers on a per-board basis; they can view the board without consuming a paid Trello seat if the Trello board uses a Workspace with Free-tier settings. We map by email match. Any Kantree member without a matching Trello account is held in a reconciliation queue for the customer's admin to provision before card import.
Kantree
Role and Permission
Trello
Workspace or Board Permission
lossyKantree roles define workspace and project-level permissions (card edit, comment moderation, field visibility, view sharing). Trello uses Workspace-level admin, normal, and observer roles, and board-level admin, member, and observer roles. We map the highest applicable permission level per user across the Kantree workspace (if a user is admin at workspace level, they become Workspace Admin in Trello; if they are project-level observer only, they become board Observer). Fine-grained field-level visibility settings do not map and are documented as manual configuration steps.
Kantree
View (Table, Matrix, Timeline, Calendar, Gantt)
Trello
Board or Power-Up View
lossyKantree's non-Kanban views (Table, Matrix, Timeline, Calendar, Gantt) have no direct Trello equivalent. We export the view definitions including filters, sort orders, displayed fields, and grouping configuration as a written view inventory. Trello Standard and above offer Calendar and Timeline views natively; Table view requires Premium. The customer chooses which Kantree views to recreate in Trello Power-Ups or as separate boards with filtered card-template lists.
Kantree
Automation
Trello
Butler or Power-Up
lossyKantree automations consist of KQL-based triggers, conditional branches, and action chains (set field, move card, post comment, copy card, etc.). Trello Butler supports trigger-action rules with at most one conditional branch. Complex Kantree automations with multi-step chains, KQL filter conditions, or card-count triggers do not map to Butler. We export the complete automation rule inventory — trigger type, conditions, action chain — as a written document organized by project, and the customer's admin rebuilds in Butler or selects a Power-Up with equivalent logic.
Kantree
Form
Trello
Trello Form or External Tool
lossyKantree public-facing forms that create cards on submission are configuration artifacts. We export form definitions (field structure, submitter info capture, validation rules) as a written inventory. Trello does not have a native form creation tool; the customer can use Trello Butler's card creation from form data or a third-party form tool (JotForm, Typeform, Google Forms) linked via Power-Up. Form submission history migrates as cards with a 'Form Submission' label and the submitted field values as card description.
Kantree
Report
Trello
Dashboard or Power-Up
lossyKantree Reports are workspace and project-level aggregated statistics (filters, groupings, displayed fields). We export report definitions as written configuration notes. Trello Standard and above provide Dashboard views for cross-board statistics; more detailed reporting requires a Power-Up such as Screenful, Corwise, or a custom analytics integration. Historical report snapshots do not migrate as datasets and are noted as requiring manual recreation in the destination reporting tool.

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
Workspace audit and custom field inventory
We audit the full Kantree workspace hierarchy (all projects, card types, custom fields, subcard depth, relationship fields, and KQL automations) and produce a custom field reduction report. This report categorizes each custom field as natively supported in Trello (title, description, member, label, due date, checklist, attachment), replicable via a Power-Up (Custom Fields, Card Colors, due date trackers), or unfixable in Trello. We present this report to the customer's admin before migration begins and agree on the field mapping strategy, subcard handling, and relationship embedding approach. No data moves until the strategy is signed off.
User account reconciliation
We extract every distinct Kantree member from the workspace and match by email against the destination Trello Workspace. Kantree organization members (billable) map to Trello Workspace members. Project-level observers (free in Kantree) map to Trello board Observers where the destination Workspace supports observer access. Any Kantree member without a matching Trello account goes to a reconciliation queue, and the customer's admin provisions the missing accounts before board migration. Board-level permissions are mapped from Kantree workspace and project role levels to Trello Workspace and board admin/member/observer roles, with fine-grained field-level permissions documented as manual configuration steps.
Board and list structure migration
We create Trello boards in dependency order matching the Kantree project hierarchy. Each Kantree card group (column) becomes a Trello list. Card group names, card ordering within groups, and WIP limit settings migrate as list names and list header settings. If a Kantree project uses multiple card types, we create separate Trello boards per card type or use labels as a card-type proxy, depending on the scoping agreement. The board description and any project-level metadata are carried into the Trello board description.
Card migration with field mapping
We migrate cards board by board, applying the custom field mapping strategy from the scoping agreement. Standard fields (title, description, due date, assignee, label, checklist, attachment) migrate directly. Custom fields are written to Trello Custom Fields Power-Up or embedded as structured text in the card description. Subcards are flattened to checklist items. Card relationship references are embedded in card descriptions as markdown links. Card creation and modification timestamps are stored in a custom 'Last Modified' field. We use batch API calls with retry logic and emit a row-count reconciliation report after each board migration.
Comment, attachment, and engagement migration
Comments migrate as Trello card comments with author and timestamp preserved. Attachments are downloaded from Kantree's storage layer and re-uploaded to Trello cards. Files exceeding Trello's 10MB limit are flagged, and the customer chooses whether to attach via a Google Drive or Dropbox Power-Up link instead. Rich text comments convert to Trello-compatible markdown. The attachment reconciliation report lists every file that exceeded the limit with the Trello board, card, and filename for manual follow-up.
Automation inventory and view reconstruction plan delivery
We deliver the automation inventory as a structured document: one entry per Kantree automation rule with the trigger type, KQL condition logic, action chain, and a recommended Butler or Power-Up equivalent. We deliver the view reconstruction plan as a separate document: one entry per Kantree view (Table, Matrix, Timeline, Calendar, Gantt) with the filter configuration, sort order, displayed fields, and a recommended Trello approach (native view on Standard and above, Power-Up, or separate filtered board). We do not rebuild automations or views inside the migration scope.
Cutover, delta sync, and hypercare
We freeze Kantree writes 24 hours before cutover and run a final delta migration for any cards, comments, or attachments modified during the migration window. We then enable Trello as the system of record. We support a 5-business-day hypercare window where we resolve any reconciliation issues raised by the customer's team. We do not rebuild Kantree automations as Butler rules, recreate Kantree views in Trello Power-Ups, or configure Trello Power-Up subscriptions inside the migration scope.
