Migrate from GanttPRO to Trello

GanttPRO Projects map to Trello Boards. We preserve the project name as the board title, project description as the board description, and the auto-scheduling toggle state as a board note. Portfolio membership from GanttPRO maps to Trello Workspace organization; the customer chooses whether to create separate Workspaces per portfolio or group boards under a single Workspace during scoping.

GanttPRO Portfolios (Business tier) group multiple projects on a single screen. We migrate portfolio membership by organizing the resulting Trello Boards under a shared Workspace. The customer configures Workspace-level settings (visibility, permissions) during the rebuild step since Trello Workspace access control differs from GanttPRO portfolio roles.

GanttPRO Summary Tasks (parent rows that group subtasks on the Gantt chart) map to Trello Lists. We preserve the summary task name as the list name and the task's start and end dates as the list's date range note. Note that Trello Lists do not have their own date fields; the date range is added as a board description note or as card labels for reference.

GanttPRO standard Tasks map to Trello Cards. The task name becomes the card title, description maps to card description, start date maps to a custom card field (Start Date), end date maps to the card due date, priority maps to a label or custom priority field, and status maps to card position within the list. Task progress percentage does not have a native Trello equivalent; we store it as a custom number field if the Custom Fields Power-Up is enabled.

GanttPRO Subtasks nested under a summary task or standard task become Checklist items on the parent Trello Card. We preserve the subtask name as a checklist item and the subtask's assignee as a @mention in the checklist item note. Subtask dates and status do not map natively; we flag them for manual review as the customer may prefer to elevate high-priority subtasks to separate Cards.

GanttPRO's four dependency types (Finish-to-Start, Start-to-Start, Finish-to-Finish, Start-to-Finish) map to Trello's 'Blocks' and 'Blocked by' card connections. We migrate the blocking relationship direction but cannot preserve dependency type differentiation in Trello. Circular dependency chains are flagged as warnings. Note that Trello's free blocking requires manual setup or a Power-Up; we provide a written dependency map for the customer's admin to rebuild.

GanttPRO milestones (diamond markers on the timeline) map to Trello Cards with a dedicated milestone label or as Cards in a dedicated milestone list. We preserve the milestone name and due date as the card title and due date. Milestones do not have a first-class equivalent in Trello; the label approach is the standard workaround.

GanttPRO project members (human users assigned to tasks) map to Trello Board members by email match. We resolve every distinct assignee referenced on GanttPRO tasks and map them to Trello members. Virtual resources (role-based placeholders with cost rates) are extracted as task-level notes because Trello has no virtual resource concept; the customer reviews these and assigns them to real members post-migration.

GanttPRO custom fields (Advanced tier and above) map to Trello Custom Fields Power-Up where types align: GanttPRO text to Trello text, number to number, date to date, list to dropdown, multiselect to dropdown (with multi-select note), label to label, people to member field. Color fields map to Trello label colors. Field-level permissions do not have a Trello equivalent; custom field visibility is board-level only.

GanttPRO time entries (date, user, hours, comment) map to Trello Card attachments (JSON export) or as a custom number field holding total logged hours. Time log export is only available in XLSX format from GanttPRO; we convert the file to structured JSON before import. Trello does not have a native time tracking feature; the customer may install a time tracking Power-Up as a post-migration step.

GanttPRO automatic and manual budget calculations (derived from resource rates and estimated hours) do not have a native Trello equivalent. We extract the calculated budget value and original cost entries as a structured note appended to the relevant Project Board description and flag the data for manual reconciliation. Trello has no built-in budget tracking module.

GanttPRO custom project templates (Advanced tier and above) include task hierarchy, dependencies, and default assignees. We export the template structure and note that it must be rebuilt in Trello using the Board Templates feature. Template dependencies and hierarchical task structure do not survive direct import; the customer uses the export as a specification guide for manual template creation.

GanttPRO saved filters (task name, type, assignee, status, priority, date range, color, custom fields) do not migrate to Trello. Trello has a card filter feature (by label, member, due date) but saved filter views are not transferable. We deliver a written inventory of all GanttPRO filter configurations for the customer's admin to recreate in Trello.

GanttPRO project calendars (working days, holidays, calendar exceptions) define which days tasks can be scheduled on. Trello Cards have individual due dates but no project-level working day calendar. We export the working-day configuration as a written note for the customer's admin and apply the effective working days during date conversion for card due dates.

GanttPRO file attachments on tasks are not supported for automated migration. We recommend users export attachments directly from the GanttPRO UI before migration and re-upload them to the corresponding Trello Cards post-migration. We provide a mapping file linking each task to its attachments for manual re-upload reference.
