Overview

What this migration involves

Moving from Ganttic to Trello is a structural migration that reconciles a resource-centric Gantt model against a Kanban-style card and board paradigm. Ganttic's core entity is the Resource (person, room, vehicle, or equipment) scheduled across Projects and Tasks on a visual timeline; Trello has no native Resource object and represents work as Cards moving through Lists within Boards. We map Ganttic Resources to Trello Board Members and Labels, Projects to either top-level Boards or parent Lists, Tasks to Cards, and Milestones (implemented as date Data Fields in Ganttic) to Card due dates or checklist summaries. Ganttic's nine Data Field types (List, Multi-Select, Check, Text, Number, Date, User, Link, Auto Increment) require Custom Fields in Trello, which are available only on Premium and Enterprise tiers. We flag this before migration begins so the customer confirms their Trello tier or adjusts scope. We do not migrate Ganttic Custom Views as code; we deliver a written inventory of view configurations for the customer's admin to recreate as Board settings. Reports export as CSV during discovery and are documented for manual rebuild in Trello or a connected BI tool.

Why teams make this switch

Two sides of the same decision

Leaving

Ganttic logo

Ganttic

What's pushing teams away

  • The user interface is described as clumsy by some reviewers, making navigation unintuitive compared to competitors like Wrike
  • Limited review volume (29 G2 reviews) makes it hard to gauge long-term satisfaction and support quality before committing
  • Teams outgrow Ganttic as they scale and need stronger integrations, advanced reporting, or enterprise features not fully available
  • API documentation is sparse and rate limits are not publicly documented, creating friction for automated workflows and migration tooling
  • Mid-market focus means large enterprises with complex org structures find the platform insufficient for their needs

Choosing

Trello logo

Trello

What's pulling them in

  • Free plan supports unlimited users and 10 boards, giving small teams full access to core Kanban functionality before any paid commitment is required.
  • The drag-and-drop board/card/Label interface requires no training, which reduces adoption friction and onboarding time across distributed teams.
  • Atlassian ecosystem integration with Jira, Confluence, and Bitbucket provides native cross-tool workflows for teams already using Atlassian tools.
  • Butler automation on paid tiers enables rule-based triggers without third-party integrations, covering basic workflow automation needs.
  • Simple visual task management with due dates, checklists, and member assignments keeps individual contributors and small teams organized without complexity.

Object mapping

How Ganttic objects map to Trello

Each row shows how a Ganttic 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.

Ganttic

Resources

maps to

Trello

Board Members

1:many
Fully supported

Ganttic Resources (people, rooms, vehicles, equipment) map to Trello Board Members for task assignment. A single Ganttic Resource assigned to multiple Projects on different dates resolves to one Trello Member record with Cards on multiple Boards. Resources with Data Field values (department, role, skillset) map to Custom Fields on the Member profile if Trello Premium is confirmed, or to Card Labels if the destination is a lower tier. Archived Resources in Ganttic are excluded from migration by default, reducing the customer's post-migration Ganttic plan cost.

Ganttic

Resource Grouping

maps to

Trello

Labels

1:1
Mapping required

Ganttic Resource Grouping (hierarchical groupings by Data Field values like department, location, or skillset) maps to Trello Labels. Each distinct grouping value becomes a Label with a color code. Nested groupings flatten into a single Label hierarchy per Board since Trello Labels do not support parent-child relationships. We preserve the grouping field name in the Label description for audit.

Ganttic

Projects

maps to

Trello

Board

1:1
Fully supported

Ganttic Projects map to Trello Boards. Project duration (start date, end date) maps to the Board description field, and project-level Data Fields (List, Check, Text, Number, Date) map to Custom Fields on a template Card or to Board description metadata. We create one Board per Ganttic Project, preserving the project name and any archived status as a Board label.

Ganttic

Tasks

maps to

Trello

Card

1:1
Fully supported

Ganttic Tasks map to Trello Cards. Task start and end dates map to Card due dates; assignees (Resource assignments on Tasks) map to Card Members via the Resource-to-Member lookup. Task Data Fields migrate as Custom Fields on each Card. Tasks without explicit due dates become Cards with no due date, placed in the first List of the destination Board.

Ganttic

Task Milestones (date Data Fields)

maps to

Trello

Card due date or checklist summary

lossy
Fully supported

Ganttic Milestones are date Data Fields on Projects rather than a distinct object. We extract every Project Data Field of type Date and evaluate whether it represents a milestone (named with keywords like milestone, deadline, go-live, kickoff, launch). Named milestones map to a summary Card with a due date and a checklist of dependent child Tasks. Anonymous date fields map to the parent Card's due date if the Task itself carries that date. We document the full Milestone mapping in the discovery output so the customer confirms the intended conversion strategy.

Ganttic

Project Data Fields

maps to

Trello

Custom Fields

lossy
Mapping required

Ganttic's nine Data Field types on Projects (List, Multi-Select, Check, Text, Number, Date, User, Link, Auto Increment) map to Trello Custom Fields. Custom Fields are available on Trello Premium and Enterprise plans only; Standard and Free tiers require us to map List and Multi-Select to Labels and Check to a Label color, Text to Card description, Number and Date to due date or checklist, and User to Card Members. We confirm the destination Trello tier during scoping and generate a pre-migration seed script for any picklist values in List or Multi-Select Data Fields.

Ganttic

Resource Data Fields

maps to

Trello

Custom Fields or Labels

lossy
Mapping required

Resource Data Fields (department, skillset, location, role, hourly rate) map to Trello Custom Fields on Board Members (Premium/Enterprise) or to Card Labels and checklist items (Standard/Free). Number-type fields like hourly rate map to a Custom Field of type Number or to a Card checklist item. We flag any Resource Data Field that has mandatory validation in Ganttic so the customer confirms whether that constraint applies in Trello.

Ganttic

Task Data Fields

maps to

Trello

Custom Fields

lossy
Mapping required

Task Data Fields (the same nine-type system as Projects and Resources) map to Trello Custom Fields on Cards. Multi-Select fields with multiple values per Card require Trello Custom Fields with the Multiple option enabled (Premium+). If the destination tier is Standard or Free, Multi-Select values collapse into a single comma-separated Text Custom Field. We generate the pre-migration seed script for all picklist values in List and Multi-Select Data Fields during discovery.

Ganttic

Custom Views

maps to

Trello

Board configuration documentation

1:1
Mapping required

Ganttic Custom Views define per-view time periods, grouping criteria, and filter configurations. Trello does not have a native view-configuration object, so we export all Custom View settings as part of discovery and deliver a written Board configuration document that maps each Ganttic View to a recommended Trello Board structure (List order, Label scheme, filter settings, and Power-Up recommendation). The customer's admin recreates views manually from this document.

Ganttic

Reports

maps to

Trello

CSV export and reporting inventory

1:1
Mapping required

Ganttic Reports export as CSV or PDF and may contain calculated metrics (resource utilization percentages, project completion rates, task duration summaries). We extract CSV exports during discovery to capture calculated values. Trello has no native reporting engine beyond basic Board statistics; we deliver a written reporting inventory documenting each Ganttic Report's structure and recommended Trello or third-party replacement (Atlassian Analytics, Google Sheets, or a connected BI tool).

Ganttic

Resource allocation and capacity

maps to

Trello

Card Members and due dates

lossy
Fully supported

Ganttic assigns Resources to Tasks with optional allocation percentage (e.g., Alice at 50% on Task A, 50% on Task B). Trello Cards support Member assignment but not allocation percentages. We resolve each Resource allocation by creating a Card for each distinct assignment and documenting the original allocation percentage in a Card label or Custom Field. For utilization reporting, we export a capacity summary CSV during discovery for the customer to build utilization tracking in a connected spreadsheet.

Ganttic

Project shift operations (pre-migration state)

maps to

Trello

Card due date audit snapshot

1:1
Fully supported

Ganttic's shift feature moves an entire Project along with all its Tasks and Milestones on the timeline. The documentation confirms this action cannot be automatically reversed. We capture the full pre-shift state of all Projects before migration begins so the customer's Ganttic instance remains undisturbed during parallel-run validation. The pre-migration snapshot is included in the discovery export as a JSON artifact for the customer's records.

Pair-specific challenges

  • Trello Custom Fields require a Premium or Enterprise tier

    Ganttic's nine Data Field types (List, Multi-Select, Check, Text, Number, Date, User, Link, Auto Increment) exist on Resources, Projects, and Tasks. Trello Custom Fields are available only on Premium ($5/user/month) and Enterprise ($17/user/month) plans. Standard and Free tiers cannot store structured custom data on Cards. We confirm the destination Trello tier during scoping. If the customer is on Standard or Free, we map List and Multi-Select to Labels, Check to Label color, Text to Card description, and Number/Date to Card checklist items or due dates. This is a tier-gated constraint that changes the migration scope and cost.

  • Trello has no native Gantt chart or timeline view

    Ganttic is a visual Gantt resource planner at its core. Trello is a Kanban board tool. Cards do not have a native start-date field (only due dates), and there is no timeline or Gantt view in Trello's standard interface. Teams managing project schedules with start-date dependencies cannot replicate Ganttic's timeline in standard Trello. We recommend the TeamGantt Power-Up for timeline visualization, but this requires an additional subscription and does not sync bidirectionally with Ganttic. We document the timeline limitation explicitly in the migration scope and capture date relationships as Card due dates and checklist summaries for approximate reconstruction.

  • Ganttic API rate limits are not publicly documented

    Ganttic's Help Center documents API endpoints but publishes no rate limits or quota thresholds. This creates migration risk for large data volumes. We implement adaptive throttling with exponential backoff on all Ganttic API calls, starting conservatively at 5 requests per 10-second window and ramping only when we observe response headers indicating headroom. For bulk record creation, we use Ganttic's CSV import endpoint as a fallback path that bypasses API rate uncertainty entirely. This approach is documented in our migration methodology but means that large migrations may take longer than estimated if the Ganttic API exhibits throttling behavior we discover only during execution.

  • Multi-Select Data Fields on Trello Standard map to comma-separated text

    Ganttic Multi-Select fields allow multiple values per record (e.g., a Resource tagged with both 'Python' and 'Project Management'). Trello Custom Fields on the Standard tier do not support multiple selections. We resolve this by mapping Multi-Select values to a comma-separated text Custom Field. If the destination is Trello Premium or Enterprise, we use the native Multiple option on Custom Fields. We confirm the destination tier during scoping so the customer understands whether multi-value field fidelity is preserved or collapsed.

  • Resource allocation percentages do not map to Trello Cards

    Ganttic assigns Resources to Tasks with allocation percentages (Alice 50%, Bob 50%) indicating time split across concurrent tasks. Trello Cards support Member assignment (multiple people) but not allocation percentages. We capture allocation percentages in a Card Custom Field or Label during migration. Utilization reporting based on allocation percentages requires rebuilding in a connected spreadsheet or BI tool post-migration.

Migration approach

Six steps for a successful Ganttic to Trello data migration

  1. Discovery and tier confirmation

    We audit the source Ganttic planner across Resources (active and archived), Projects, Tasks, Milestones (date Data Fields), Data Field definitions (all nine types with picklist values for List and Multi-Select), Resource Grouping hierarchies, Custom View configurations, and Report CSV exports. We pair this with Trello tier confirmation: Standard, Premium, or Enterprise. The destination tier determines whether Custom Fields are available natively or require workaround mapping (Labels, Card descriptions, checklists). The discovery output is a written migration scope with record counts, Data Field type inventory, and picklist value lists for pre-seeding.

  2. Pre-migration data seeding

    Before any records move, we generate and execute a seed script that pre-creates Labels (from Ganttic Resource Grouping values), Custom Fields (from Ganttic Data Field definitions with their types and picklist values), and Board Members (from Ganttic Resources). If the destination is Trello Standard or Free, we seed Labels only and map Data Fields to Card description or checklist formats. We validate the seed by creating a test Board with one Card before proceeding to bulk migration.

  3. Resource migration with grouping and archiving

    We migrate Ganttic Resources to Trello Board Members and Labels. Archived Ganttic Resources are flagged during discovery and excluded from migration by default, reducing post-migration Ganttic plan cost. Active Resources with Data Field values map to Labels or Custom Fields per the tier-confirmed strategy. We extract Resource Grouping hierarchies and flatten them to a single-level Label scheme per destination Board.

  4. Project and task migration in dependency order

    We migrate Projects to Trello Boards first, then Tasks to Cards within those Boards. Task-to-Card mapping preserves due dates (from Ganttic Task end date), Card Members (from Ganttic Resource assignments), and Custom Fields (from Task Data Fields). Milestones (Ganttic date Data Fields on Projects) generate a summary Card with a due date and a checklist of dependent child Tasks, documented in the discovery output for customer confirmation.

  5. Custom Field and Data Field post-processing

    We validate that all Ganttic Data Field values landed correctly in Trello Custom Fields, Labels, or Card descriptions. List and Multi-Select values are verified against the pre-seeded picklist. Any records that fail validation (e.g., a picklist value missing from the seed script) are flagged in a reconciliation report with the affected record ID, field name, and value. We do not silently skip records; the customer reviews the report before production cutover.

  6. Cutover, validation, and view rebuild handoff

    We freeze Ganttic writes during cutover, run a final delta migration of any records modified during the migration window, then enable Trello as the system of record. We deliver the Custom View inventory document (for the customer's admin to recreate as Board settings), the Report inventory (for manual rebuild in Trello or a connected BI tool), and the pre-migration snapshot of all Project shift states. We support a one-week hypercare window where we resolve any record reconciliation issues. We do not rebuild Ganttic Custom Views as Trello configurations inside the migration scope; that is a separate engagement or an internal admin task.

Platform deep dives

Context on both ends of the pair

Source

Strengths

  • Resource-based pricing aligns cost with actual usage — archived resources do not count toward billing
  • Unlimited users across all plans means no per-seat cost friction when scaling teams
  • Flexible Data Field system with nine types and no required fields suits diverse industries
  • Visual Gantt scheduling with drag-and-drop makes capacity conflicts easy to spot
  • CSV import and export for Resources, Tasks, Projects, and Data Fields supports data portability

Weaknesses

  • Sparse public API documentation and undocumented rate limits complicate automated migrations
  • Clumsy UI reported by some reviewers; less intuitive than competitors like Wrike
  • Small review volume (29 G2 reviews) makes it difficult to assess support quality reliably
  • Limited enterprise feature set causes some mid-market teams to outgrow the platform
  • Shift operations (moving project timelines) cannot be automatically reverted in Ganttic

Destination

Strengths

  • Generous free tier with unlimited users and 10 boards, the lowest barrier to entry among major project management tools.
  • Intuitive drag-and-drop Kanban interface requires no training or onboarding documentation.
  • Deep Atlassian integration with Jira, Confluence, and Bitbucket for teams already in the ecosystem.
  • Built-in Butler automation covers rule-based triggers without requiring third-party integrations.
  • REST API with comprehensive documentation enables programmatic access to all core objects.

Weaknesses

  • Reporting and analytics are absent, with no built-in velocity tracking, burndown charts, or historical performance metrics.
  • The flat board/list/card data model scales poorly for complex projects requiring hierarchical task structures.
  • Customization is limited compared to platforms like Asana, monday.com, or Jira that offer richer field types and workflow configuration.
  • Advanced views (Timeline, Dashboard) require Premium and are not available on Standard, inflating total cost for teams needing visibility features.
  • Guest user billing rules are confusing and prone to accidental seat overages when guests join multiple boards.

Most migrations land between three and five weeks for under 500 Resources, 50 Projects, and 2,000 Tasks with straightforward Data Field mapping and Trello Premium confirmed. Migrations with complex multi-type Data Fields (List, Multi-Select, Check requiring value mapping), nested Resource Grouping hierarchies, or archived-record culling to reduce Ganttic plan costs move to six to ten weeks because of seed script generation, Custom Field pre-creation per type, and the milestone conversion design work.
