Overview
Moving from Taskworld to Trello is a structural simplification in the direction of migration. Taskworld organizes work with Projects (Kanban, Timeline, Calendar views), nested Tasks with assignees, followers, checklists, and custom fields scoped per-project. Trello uses a flatter Board-and-Card model where Lists represent stages, Cards represent tasks, and checklists live as card sub-items. We extract the full Taskworld workspace via GraphQL, map Projects to Boards with their Lists preserved as columns, and flatten nested Tasks into cards while retaining hierarchy in checklist form where Trello does not natively support sub-task depth. Custom fields defined per-project in Taskworld are extracted with their definitions and values, then re-created as Trello Custom Fields (Power-Up) or label sets depending on the destination plan tier. Task dependencies (blocks/blocked-by) migrate as card labels with a dependency label convention or are flagged for Trello's native Dependency Power-Up. We do not migrate Automations or Chat as functional code; we deliver a written inventory of each for the admin to rebuild using Trello Butler or Power-Ups.

Object mapping
Each row shows how a Taskworld 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.
Taskworld
Workspace
Trello
Workspace (Trello Workspace)
1:1Taskworld's Workspace is the top-level container holding all Projects, Members, and settings. We map workspace-level organization metadata (name, description, member list) directly to a Trello Workspace. Guest collaborators in Taskworld (up to 30 on Business) do not have direct Trello equivalents; they are mapped as Workspace members at the Standard tier or flagged for manual invitation post-migration. On Trello Enterprise, guest management policies are controlled separately by the workspace admin.
Taskworld
Project
Trello
Board
1:1Each Taskworld Project maps to a Trello Board. The project's name, description, color label, and member list transfer directly. Taskworld's default view setting (Kanban, Timeline, Calendar) has no native Trello equivalent; we note the original preference and apply Kanban as the destination default since Trello is built around list-based boards. Projects with Timeline/Gantt views are flagged for the Timeline Power-Up if the destination plan supports it.
Taskworld
Task
Trello
Card
1:1Taskworld Tasks map to Trello Cards. Assignee transfers as Card member; due date transfers as the due date field; priority level transfers as a color label (red for high, orange for medium, green for low, blue for none); description transfers as card markdown. Completed status maps to a closed card or a card moved to a Done list. Labels from Taskworld tags transfer as Trello labels with the original tag string preserved.
Taskworld
Subtask
Trello
Checklist Item
1:manyTaskworld nested subtasks (tasks within a parent task) have assignees, due dates, and checklists of their own. Trello has no native subtask object. We convert top-level subtasks to checklist items under the parent card. If a subtask itself contains a nested checklist, we flatten it to a single-level checklist set under the parent card and flag any subtask with a sub-checklist for manual rebuild as a child card using the Hierarchy Power-Up. Percent-complete displayed on the Taskworld task is recalculated from the checklist completion ratio in Trello.
Taskworld
Checklist
Trello
Checklist
1:1Taskworld checklist items migrate directly to Trello checklist items under the corresponding card. Completion status is preserved. If a checklist item is a standalone item (not tied to a subtask), it transfers as a plain checklist entry. Checklist item order within the parent task is preserved in the card checklist sequence.
Taskworld
Custom Field (project-scoped)
Trello
Custom Field (board-scoped)
lossyTaskworld custom fields are defined per-project via the Customize panel, meaning the same attribute (e.g., Customer Name, Priority Level) must be defined separately in each project. We extract all project-level custom field definitions and their values across the workspace. In Trello, the Custom Fields Power-Up applies board-wide: we consolidate duplicate custom field definitions from multiple Taskworld projects into a single custom field per board, avoiding the per-project repetition. The customer must install the Custom Fields Power-Up on each destination board before migration.
Taskworld
Task Dependency (blocks/blocked-by)
Trello
Label or Dependency Power-Up
1:1Taskworld stores directional task dependencies (blocks/blocked-by) as properties on the task object. Trello has no native dependency tracking at the free or standard tiers. We resolve the dependency graph during extraction and apply it in one of two ways depending on the destination plan: at Premium and Enterprise, we use the Card Dependencies Power-Up API to create explicit dependency links; at Standard, we apply a labeled convention (e.g., DEP-BLOCKED-BY: card name) as a card label so the admin can visually reconstruct the dependency chain post-migration.
Taskworld
Attachment and File
Trello
Card Attachment
1:1Taskworld file attachments stored on tasks are downloaded from Taskworld storage and re-uploaded as Trello card attachments. We preserve the original filename, file type, and upload date. Files exceeding Trello's 10MB per-attachment limit (or 250MB on Enterprise) are flagged and provided in a manifest for manual handling. Trello Enterprise allows larger file sizes via admin-configured attachment settings.
Taskworld
Comment
Trello
Card Comment
1:1Taskworld task-level comments migrate as Trello card comments with the original comment text, author attribution, and timestamp preserved. Taskworld's separate project chat messages do not have a direct Trello equivalent; we migrate chat message text as comments on the most recently updated card within that project or flag them for a manual move to a project documentation tool. Author attribution resolves by matching email against the Trello workspace member list.
Taskworld
Time Entry
Trello
Card Cover or Checklist Item with Duration
1:1Taskworld time entries logged against tasks have start time, duration, and optionally a description. Trello has no native time tracking field. We extract logged time entries and store the duration as a custom field on the card (if the Custom Fields Power-Up is installed), or as a checklist item with a formatted duration string. Time entry metadata (total hours, billable flag if present) is preserved in the migration manifest for the admin to configure in a Trello time-tracking Power-Up if needed.
Taskworld
User and Guest Collaborator
Trello
Workspace Member
1:1Taskworld workspace members and guest collaborators (up to 30 on Business) map to Trello workspace members by email. Full members become active Trello workspace members; guests without an email-matched Trello account go to a reconciliation queue. Role mapping (admin, member, guest) in Taskworld translates to Trello Workspace Admin or normal Member. On Trello Enterprise, SAML SSO provisioning is a separate admin step post-migration.
Taskworld
Tag and Label
Trello
Label
1:1Taskworld tags (applied to tasks and projects for categorization) migrate as Trello card labels. Tag strings are preserved exactly; color assignment uses Trello's default label colors unless the customer specifies a color mapping during scoping. Tag hierarchy (if used in Taskworld) is flattened to a single-level label string. Labels are applied at the card level for task tags and at the board level for project-level tags.

Taskworld gotchas
GraphQL API is the sole programmatic extraction method
Custom fields scoped per-project not globally
Completed task visibility state transfers as a setting
Storage limits by plan tier affect file migration completeness
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
Discovery and scoping
We audit the Taskworld workspace via GraphQL across all Projects, Tasks, Subtasks, Checklists, Custom Field definitions, Attachments, Comments, Chat messages, Time Entries, and Members. We extract workspace metadata including storage usage, active user count, and plan tier. We pair this with a Trello destination audit: workspace configuration, board count, and plan tier (Standard, Premium, or Enterprise) to determine which Power-Ups are available for custom fields, dependencies, and file size handling. The discovery output is a written migration scope with object counts, a custom field consolidation map, and a timeline estimate.
Custom field consolidation design
We review all Taskworld custom field definitions across every project, identify duplicates that share the same attribute name and data type, and consolidate them into a single custom field per Trello board. We define the mapping of Taskworld field types (text, number, date, dropdown) to Trello Custom Field Power-Up types. The customer installs the Custom Fields Power-Up on each destination board before data migration. We also design the label color mapping for Taskworld priority levels and tags.
Trello workspace and board scaffold creation
We create the Trello workspace structure based on the Taskworld project hierarchy. Each Taskworld Project becomes a Trello Board. We create Lists within each board to represent Taskworld task stages (To Do, In Progress, Done) or preserve the existing list names from Taskworld if the project used a Kanban view. Members are invited to the workspace and mapped by email against the Taskworld member list. The scaffold is validated in a Trello sandbox board before full migration begins.
GraphQL extraction with pagination and dependency resolution
We extract all Tasks, Subtasks, Checklists, Comments, and Custom Field values via Taskworld's GraphQL endpoint using cursor-based pagination. Task dependency links (blocks/blocked-by) are resolved during extraction by building a lookup table of task IDs. We also extract file attachment URLs and download binary files for re-upload to Trello. Large workspaces run extraction across multiple sessions with resumable cursors. We validate total record counts against the Taskworld workspace dashboard before proceeding.
Data transformation and mapping
We transform extracted records into Trello-compatible JSON payloads. Tasks become Cards with members, due dates, labels, and descriptions. Subtasks without nested checklists become checklist items; subtasks with nested checklists are flattened with a depth marker. Task dependency pairs are converted to labels (Standard tier) or Dependency Power-Up API calls (Premium/Enterprise). Chat messages are processed separately for the Trello comment or documentation-flag path. Time entries are stored as custom field values or checklist notes depending on the Custom Fields Power-Up availability.
Import, dependency restoration, and cutover
We import cards into Trello boards using the Trello API with batch chunking. Custom Field values are applied after card creation using the Custom Fields Power-Up API. Dependency links are restored using the Dependency Power-Up API for Premium and Enterprise destinations or applied as labels for Standard. File attachments are re-uploaded to Trello; files exceeding the plan limit are skipped and manifest. We freeze Taskworld writes during the final cutover delta, run a last-pass extraction for any records modified during migration, then complete the Trello import. We deliver a written inventory of Taskworld Automations for rebuild in Trello Butler or via Power-Up.
