Overview
Moving from Freelo to Trello is a structural simplification. Freelo's four-level hierarchy (Projects, To-Do Lists, Tasks, Subtasks) flattens into Trello's three-level model (Boards, Lists, Cards) where Subtasks become Checklist items. The key migration risks are structural: Freelo's free plan caps at 3 projects and 3 users and triggers an asynchronous ZIP export with a 1-2 day delivery window that we must coordinate before cutover, and Trello's free plan does not support custom fields at all, requiring a plan upgrade or manual rebuild of Freelo's deadline, priority, and dropdown fields. We handle file attachments, preserve comments with markdown formatting, map user accounts by email, and flag archived cards that cannot be retrieved via Trello's export API. Time tracking and cost entries from Freelo have no native Trello equivalent; we embed them as structured checklist items or card description text but note this does not preserve reporting capability.

Object mapping
Each row shows how a Freelo 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.
Freelo
Project
Trello
Board
1:1Each Freelo Project maps to a Trello Board. We map project name, description, status (active/archived), and creation date to board metadata. Freelo's project-level settings (budget, hourly rate) have no Trello equivalent and are flagged for manual note-taking post-migration. If the customer has more than 1 active board, we note that Trello's free plan has no per-workspace board count limit, only per-file and per-board storage caps.
Freelo
To-Do List
Trello
List
1:1Each Freelo To-Do List maps to a Trello List within the parent Board. We preserve the list ordering as a Trello list-position value derived from the Freelo sort order. Freelo's To-Do List-level pinned notes migrate as the first card in the list with a [NOTE] prefix in the card title to distinguish them from task cards.
Freelo
Task
Trello
Card
1:1Each Freelo Task maps to a Trello Card within the parent List. We map title, description (markdown preserved), deadline (to due date), assignee (to card member), author, creation date, completion status, and comment count. Freelo's task priority maps to Trello card label colors if labels are configured on the destination board; otherwise it is noted as a custom field candidate.
Freelo
Subtask
Trello
Checklist item
1:1Freelo Subtasks map to Trello Checklist items within the parent Card. Each Freelo subtask title becomes a checklist item, and the completion status maps to the checklist item checked state. Subtask assignees and deadlines within a checklist are not natively supported in Trello; we add them as text suffixes in the checklist item title and flag for admin review post-migration.
Freelo
User / Coworker
Trello
Workspace Member
1:1Freelo user accounts (Admin, Project Manager, Member) map to Trello Workspace Members by email address match. We export the user's name, email, and Freelo role and present this to the customer's admin for Trello permission group assignment. Freelo's role model does not have a direct Trello equivalent; the admin assigns Trello-level permissions manually post-migration.
Freelo
File / Attachment
Trello
Card Attachment
1:1Freelo file attachments migrate as Trello card attachments. We pull binary files via the Freelo API and upload to Trello via the attachments endpoint. A key gotcha: Trello's free plan limits files to 10 MB each versus Freelo's 100 MB ceiling. We validate file sizes before upload; files exceeding the destination plan's limit are flagged for re-hosting (Google Drive, Dropbox) and linking as a URL attachment, with the original file name preserved as the link label.
Freelo
Comment
Trello
Card Comment
1:1Freelo comments attached to Tasks or To-Do Lists migrate as Trello card comments. We map comment body, author, and timestamp. Markdown formatting in Freelo comments is preserved as-is in the Trello comment. Freelo pinned comments on To-Do Lists migrate as the first card comment on the corresponding list's introductory note card (created as a [NOTE] card per the To-Do List mapping).
Freelo
Custom Field
Trello
Custom Field
lossyFreelo custom fields on Tasks (text, number, date, dropdown) map to Trello Custom Fields via the Custom Fields Power-Up. Trello Standard ($5/user/mo) and Premium ($10/user/mo) include the Custom Fields Power-Up; the Free plan does not support it. If the destination workspace is on Free, we export custom field name-value pairs as structured text in the card description under a [CUSTOM FIELDS] heading and note the plan upgrade requirement for the admin. Dropdown values migrate as Trello dropdown options; date values as Trello date fields; number values as Trello number fields.
Freelo
Tag
Trello
Label
lossyFreelo tags on Tasks map to Trello Labels on the destination Board. Trello limits labels to 10 per board versus Freelo's unlimited tag count. If the source project uses more than 10 distinct tags, we present a consolidation plan to the admin during scoping, grouping related tags by color and retaining the most-used tag names. Tag colors from Freelo are not available in the API; we assign Trello label colors arbitrarily by mapping order.
Freelo
Time Entry
Trello
Checklist item or card description
lossyFreelo time entries (duration and cost per task) have no native Trello equivalent. We export duration, cost value, and currency per task and embed them as structured checklist items: [ ] Duration: Xh Ym | [ ] Cost: $Z in a dedicated Time Tracking checklist on each card, and additionally as a text block in the card description. We flag to the customer that this is a manual workaround and does not enable time-based reporting within Trello; billing summaries require a third-party Power-Up or manual extraction.
Freelo
Cost tracking
Trello
Card description
lossyFreelo task-level cost tracking (hourly rate × logged time) migrates as structured text in the card description under a [BUDGET] heading. The original budget amount, logged cost, and currency are preserved as human-readable text. Trello does not have a native cost or budget field on cards.
Freelo
Recurring Task
Trello
Butler rule (post-migration)
lossyFreelo supports recurring tasks with repeated budget settings. Trello automates recurring card creation through Butler rules (included in Standard and Premium) or third-party Power-Ups. We document each Freelo recurring task pattern (frequency, budget, assignee) in the automation inventory deliverable so the admin can configure equivalent Butler rules post-migration.

Migration approach
Scoping and export coordination
We audit the source Freelo account: active project count, task and subtask volume, attachment count and size distribution, custom field names and types, user count, and time-entry volume. We check the source plan tier — if the account is on Free, we confirm project and user counts are within the 3-project and 3-user cap before migration begins to avoid silent record exclusion. We trigger the async ZIP export immediately so it arrives within 1-2 days and set up the Trello workspace structure in parallel. We present a Trello plan recommendation (Free vs Standard vs Premium) based on custom-field usage and file-size distribution.
Data extraction and transform
When the Freelo ZIP export arrives, we extract the JSON payload and cross-reference it against the Freelo REST API to ensure record completeness. We transform the four-level Freelo hierarchy into Trello's three-level structure: Projects become Boards, To-Do Lists become Lists, Tasks become Cards, and Subtasks become Checklist items. We build a label consolidation map if tag count exceeds Trello's 10-label board limit. We extract custom field values and custom field types from the Freelo export and pre-build the Trello Custom Fields Power-Up schema (field names, types, options) for Standard and Premium destinations. Time entries and cost values are extracted as structured text blocks for embedding.
Test migration
We run a full migration into a test Trello workspace using production-like data volume. The customer reconciles record counts (boards in, lists in, cards in, subtask checklists in, comments in, attachments in, custom field values in) against the Freelo source. We spot-check 25-50 random cards for content accuracy, checklist completeness, and file attachment presence. The customer signs off the test migration before production migration begins. Any mapping corrections — label consolidation choices, custom field schema adjustments, label-color assignments — are resolved in this phase.
Production migration
We run production migration in dependency order: Boards first, then Lists, then Cards with parent List resolved, then Checklist items with parent Card resolved, then Comments, then Custom Field values (Standard and Premium only), then Attachments (with file-size validation and re-hosting for oversized files), then Labels. Each phase emits a row-count reconciliation report before the next phase begins. We use Trello's REST API with rate-limit awareness (adaptive throttling based on 429 responses) to stay within Trello's throughput limits.
Cutover and delta sync
We coordinate a Freelo write-freeze window with the customer's team. Any tasks modified during the migration window are identified via a timestamp filter and migrated as a delta pass. We enable Trello as the system of record at cutover. We validate 20-30 cards post-migration for content and attachment integrity and surface any gaps. We deliver the automation inventory document listing recurring task patterns requiring Butler rule rebuild, the archived-card gap report, and the time-tracking workaround documentation for admin review.
Hypercare and handoff
We support a one-week hypercare window where we resolve reconciliation issues raised by the customer's team. We do not rebuild Freelo recurring tasks as Butler rules as part of the migration scope; the automation inventory deliverable gives the admin the configuration guide to do this independently. We do not provide post-migration training on Trello, Butler, or the Custom Fields Power-Up; these are separate engagements. Trello onboarding resources (Atlassian University, Trello help center) are recommended for team-wide adoption.
