Overview
Moving from Twproject to Trello is a structural simplification: Twproject's Gantt WBS, resource allocation, cost tracking, and hierarchical task model compress into Trello's flat board-card architecture. We extract worklogs and costs via direct API calls because the Twproject project JSON export explicitly omits both, then map Projects to Boards, Phases to Lists, and Tasks to Cards with subtasks as checklist items. We flag upfront that Trello has no native Gantt, resource workload view, or cost tracking — teams that rely on these Twproject features receive a written gap analysis and a Power-Up recommendation for post-migration continuity. We do not migrate Twproject ToDos or attachments, both of which are absent from the JSON export and have no Trello equivalent. We do not migrate automations; Twproject's workflow rules and Trello's Butler rules require separate rebuild scope.

Object mapping
Each row shows how a Twproject 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.
Twproject
Project
Trello
Board
1:1Each Twproject project becomes a Trello board. We create the board in the target workspace, set visibility (public or private), and import the project name, description, start date, and target end date as board metadata. Trello's board-level metadata fields are limited compared to Twproject's project detail view, so dates migrate as card due dates or as a pinned board description note. Multi-phase projects in Twproject map to multiple Trello lists within the board (see Phase/List mapping below). Teams should decide on a board-naming convention and workspace assignment before migration begins.
Twproject
Phase / Sub-project
Trello
List
1:manyTwproject's hierarchical project structure (project > phase > sub-phase > task) has no direct Trello equivalent. Trello supports only two levels: Board > List > Card. We flatten the hierarchy by mapping the top-level Twproject phase to a Trello List, and any nested sub-phases are handled as either additional Lists within the same board or as Card labels to preserve the original hierarchy signal. We document the original WBS path as a card label or as the first line of the card description during scoping so the admin can decide on the best flattening approach for their team.
Twproject
Task
Trello
Card
1:1Twproject tasks map directly to Trello cards. We preserve the task name as the card title, description as the card description (rich text), due date as the card due date, priority from Twproject's urgency field as a Trello Label (color-coded), and assignee as the card member. Twproject's parent-child subtask relationship maps to Trello checklist items within the parent card rather than as separate cards — this preserves the hierarchy within the card boundary while keeping the board flat. Task status in Twproject maps to the card's current list position or to a dedicated Done/Closed list.
Twproject
Resource (User)
Trello
Member
1:1Twproject Resources (user accounts with allocation and cost rate metadata) map to Trello workspace Members. We resolve by email match and map the user's Twproject display name to the Trello full name. Cost rate data from Twproject has no Trello native equivalent — we document it as a custom card field (if Business Class is purchased) or as a note in the card description. We also flag any Twproject Resource without a corresponding Trello account to the customer's admin for member provisioning before the card migration phase begins.
Twproject
Worklog
Trello
Card Description / Checklist Item
lossyWorklogs are not included in Twproject's project JSON export. We extract them via direct API calls using the task ID association, pulling date, hours, user, and notes. Trello has no native time-entry object, so we embed worklog data as either a structured card description entry (date + hours + user) or as a read-only checklist item on the related card. Worklogs that represent billable hours should be migrated to a dedicated time-tracking Power-Up (such as Timesheet by Greep or Plinq) post-migration, which we recommend during scoping. Date-range scoping applies to limit extraction to the relevant active-project window.
Twproject
Cost and Budget
Trello
Card Description / External Documentation
lossyTwproject's Costs & Revenues section (budget-vs-actual forecasts) is excluded from the project JSON export and fetched separately via API. Trello has no cost-tracking feature at any tier. We document cost data as structured text in the related card description and deliver a written cost data export as a supplementary CSV. For teams that need ongoing budget tracking, we recommend establishing a separate financial Power-Up or tool post-migration. Cost records are flagged as not migratable-native during scoping so the customer can plan accordingly.
Twproject
Custom Field
Trello
Custom Field
lossyTwproject custom fields (wizard-driven on tasks and projects) are retrieved via API and mapped to Trello Custom Fields. Trello Custom Fields are available on Standard ($6/user/month) and Business Class ($10/user/month) plans only — the free tier does not support them. We enumerate all Twproject custom field definitions during discovery, map data types to Trello's Custom Field types (text, number, date, checkbox, single-select, multi-select), and import values per card. If the customer is on Trello Free, we flag the limitation and recommend a plan upgrade or note which fields cannot be preserved.
Twproject
Gantt / WBS Structure
Trello
Labels + Timeline Power-Up
lossyTwproject's Gantt WBS (phases, sub-phases, tasks with start dates, end dates, dependencies, and milestones) has no native Trello equivalent. Trello natively stores only card title, description, due date, member, label, and list position. We map task start and end dates to card due dates and start dates, map the WBS phase path to a label (e.g., Phase-1-Design), and document the full dependency tree in a separate CSV for manual rebuild. Trello's Timeline Power-Up (Business Class) provides a Gantt-style view after migration but must be installed and configured post-migration — dependencies are not automatically re-created in Timeline.
Twproject
Kanban View (Twproject daily planning)
Trello
Lists
lossyTwproject's Kanban is a daily planning view rather than a top-level project object, driven by task status and assignments. We migrate the underlying task data (assignee, status, dates) which populates Trello's board views naturally. The Kanban board configuration itself (columns, swimlanes, WIP limits) is Twproject-specific and does not transfer — we document the column names and any WIP limit settings as a written reference for the customer's admin to reconfigure in Trello Lists or in a Power-Up.
Twproject
Tags
Trello
Labels
1:1Twproject tags on tasks and projects map to Trello Labels. We retrieve tag assignments via API, normalize them to Trello label names, and apply color assignments where Twproject uses a color taxonomy. Some Twproject tags may be flat while Trello labels are per-board — we note any workspace-level labeling strategy during scoping so tags used across multiple projects are handled consistently.
Twproject
MS Project Import/Export data
Trello
Card metadata
lossyTwproject supports MS Project file import and export for projects that originated in Microsoft Project. We include MS Project metadata (task hierarchy, durations, dependencies) as card description notes or as labels if the project originated externally and the MS Project data is the primary record. We flag this during scoping to determine whether the MS Project import data is the authoritative source or supplementary.
Twproject
Resource Allocation / Workload
Trello
Member assignment on cards
lossyTwproject's resource workload view shows assignment distribution across time periods per resource. Trello has no workload view — card membership is the only allocation signal. We map Twproject assignment data to card members, and document per-resource assignment load in a written CSV (resource, task, allocation percentage, date range) for the customer's admin to use when rebuilding workload visibility in a Power-Up or external resource management tool.

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.
Twproject gotchas
Project JSON export excludes worklogs, costs, and attachments
API authentication tied to individual user credentials
On-premise deployments use customer-specific server URLs
License count is based on enabled users, not active assignments
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 inventory every Twproject object in scope: projects, tasks, subtasks, resources, custom field definitions, worklogs, costs, and tags. We confirm the Twproject deployment type (cloud or on-premise, which determines the API base URL), collect admin credentials for a dedicated migration user, and verify the API key validity. We count active projects and map them to the target Trello workspace, identify the board-count relative to the workspace plan, and enumerate which Twproject objects are live data versus historical archive. The discovery output is a written migration scope document with an explicit exclusion list for objects that cannot migrate natively.
Board-structure design
We work with the customer's admin to map each Twproject project to a Trello board and each Twproject phase or status to a Trello list. We define the label taxonomy (matching Twproject tags and priority levels to Trello label names and colors) and confirm which Twproject custom fields map to Trello Custom Fields. We verify the Trello workspace plan supports Custom Fields and confirm the board count does not exceed the plan limit. This step must complete before any data is extracted because the list and label definitions are required during the card creation phase.
Extraction from Twproject API
We extract data from Twproject via the REST API using the dedicated admin account credentials. We run the project JSON export as a baseline, then supplement with separate API calls for worklogs (fetched by task ID), costs (fetched from the Costs & Revenues section), custom field values, resource allocation records, and tag assignments. We flag any API call that returns a credential or rate-limit error and retry with exponential backoff. Attachments and ToDos are confirmed absent from the API export path and documented as excluded.
Transformation and staging
We transform extracted records into Trello card JSON format: task name becomes card title, Twproject description becomes card description (with worklog entries appended as structured text), priority becomes a label, dates become card due dates, and subtasks become checklist items. We resolve Twproject resource IDs to Trello member email addresses (using the user mapping built during discovery), and map Twproject custom field values to Trello Custom Field values per card. The staging output is a set of per-board card batches ready for Trello API import.
Load into Trello and reconciliation
We create boards in the target Trello workspace via the Trello REST API, then create lists within each board, then import cards in batches per list. We apply labels, members, due dates, and custom field values after card creation using the card ID returned from the create call. We run a row-count reconciliation against the Twproject extraction (projects in, boards created; tasks in, cards created; resources in, members assigned) and flag any discrepancies. We do not migrate archived Trello cards from any source because Twproject does not have an archived-card equivalent.
Cutover and handoff
We freeze writes in Twproject during cutover, run a final delta extraction of any records modified during the migration window, and apply the delta to Trello. We deliver the excluded-objects inventory (worklogs, costs, ToDos, attachments) as a written CSV and a gap analysis recommending Power-Up replacements for Gantt, time tracking, and cost management. We deliver the board-structure map (Twproject project to Trello board) and the custom field mapping reference. We do not rebuild Twproject workflows or Trello Butler rules as part of the migration scope; that is a separate engagement.
