Overview

What this migration involves

PlanZone and Trello have fundamentally different data models. PlanZone is a hierarchical, Gantt-oriented tool where Projects contain nested Tasks with parent-referenced dependencies and milestone flags. Trello is a Kanban board tool where Boards contain Lists containing Cards, with dependencies expressed as separate linked-card relationships. Because PlanZone publishes no public API, migration requires a customer-originated CSV export from the UI, which determines the field coverage window. We walk the PlanZone project tree to preserve parent-child relationships, convert flat dependency links into Trello card connections, and carry milestone dates as card due dates with a milestone label. We do not migrate PlanZone Templates, Workflows, or Gantt-chart configurations; these are documented in the scope agreement for manual rebuild in Trello or Butler. Trello's Free tier caps workspaces at 10 Boards, which is a common constraint for PlanZone customers with multiple active projects, and we surface this during scoping so the workspace tier decision is made before migration begins.

What's pushing teams away

  • API capability is referenced but limited per multiple reviewer sources — teams wanting deep automation often hit gaps that competitors like Asana or Monday cover natively.
  • Smaller market footprint outside France means thinner integration ecosystem and partner network compared with international project management leaders.
  • Pricing per user (Basic €20, Team €17, Business €15) scales with seat count and can exceed cheaper flat-rate competitors for larger teams.
  • English-language documentation and reviewer presence are thinner than for international PM tools, slowing onboarding for non-French teams.
  • Mobile experience and offline capabilities lag market leaders like Asana and ClickUp.

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 PlanZone objects map to Trello

Each row shows how a PlanZone 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.

PlanZone

Project

maps to

Trello

Board

1:1
Fully supported

PlanZone Projects map to Trello Boards as the top-level container. Each project name becomes the board name, and the project description migrates as the board description. We extract all projects from the CSV export and create one board per project during the load phase. If the customer uses PlanZone's template feature to spawn projects, we note the template origin on each board as a custom label so the admin can decide whether to use Trello's Board Templates feature for recurring setup.

PlanZone

Task

maps to

Trello

Card

1:1
Fully supported

PlanZone Tasks map to Trello Cards with the task name as card title, description as card body, assignee as card member, and due date migrated as card due date. We preserve the parent-child hierarchy by creating cards under the correct board and resolving the list assignment from the PlanZone stage (see Stage → List mapping). Task priority migrates as a Trello label with a priority color mapping so the admin can filter by priority across boards.

PlanZone

Stage

maps to

Trello

List

1:1
Fully supported

PlanZone task stages (e.g., Not Started, In Progress, Review, Done) map to Trello Lists within the destination Board. We extract all distinct stage values from the PlanZone CSV for each project and create corresponding lists. Stage ordering is preserved by creating lists in the order they appear in PlanZone. If PlanZone uses custom stage names, we carry them verbatim into Trello list names so the admin can rename them post-migration if desired.

PlanZone

Milestone

maps to

Trello

Card (due date + label)

lossy
Fully supported

PlanZone milestones are a flag on a task record with a target date and milestone name. We migrate milestone-flagged tasks as Trello Cards with the milestone name as card title, the milestone target date as card due date, and a Milestone label (we use a dedicated label color) to distinguish them from regular tasks. The admin can then use the Due Date power-up or Trello's calendar view to visualize milestone timing. There is no native milestone object in Trello, so this configuration is the standard workaround.

PlanZone

Dependency

maps to

Trello

Card (linked card)

lossy
Fully supported

PlanZone stores task dependencies as a linked field on the child task pointing to the parent task ID. Trello has no native dependency object; dependencies are represented as card connections using the Card Links power-up or by adding the parent task name as a checklist item on the child card. We convert PlanZone's flat parent-reference format to one of these two strategies based on the customer's preference during scoping. The dependency resolution step must be validated before the load phase because it affects the checklist count and card structure.

PlanZone

Custom Fields

maps to

Trello

Custom Fields Power-Up

lossy
Mapping required

PlanZone custom fields on Projects and Tasks are discovered during the schema audit step from the CSV column headers. We map each PlanZone custom field to a Trello Custom Fields Power-Up field of the matching type (text, number, date, dropdown). Trello Custom Fields is available from the Premium tier ($10/user); if the destination workspace is on the Free or Standard tier, we flag this as a tier upgrade requirement during scoping. The admin must enable the Custom Fields power-up on each destination board before migration.

PlanZone

User / Assignment

maps to

Trello

Member

1:1
Fully supported

PlanZone assigns tasks to users by email reference in the assignee field. We extract all distinct assignee emails from the CSV and match them against the Trello workspace member list. Members without a match in Trello are held in a reconciliation queue; the admin provisions new workspace members before the load phase runs. On Trello, a member added to a card is the equivalent of a PlanZone task assignment.

PlanZone

Comment

maps to

Trello

Card Comment

1:1
Fully supported

PlanZone task comments migrate as Trello card comments. We extract comment text, author email, and timestamp from the CSV. Comments are attached to the correct card by matching the parent task name. Trello comment ordering is chronological by timestamp. Large comment threads on individual cards may affect card rendering in Trello's UI, so we flag cards with more than 20 comments as a review item during the QA step.

PlanZone

Attachment

maps to

Trello

Card Attachment

1:1
Fully supported

PlanZone file attachments are referenced by URL in the CSV export. We re-upload each attachment as a Trello card attachment during the load phase, using the original filename. Attachments are tied to the correct card by matching the parent task. If an attachment URL is inaccessible (expired link, private storage), we flag it in the attachment manifest delivered with the scope agreement and note it as a manual-recreate item.

PlanZone

Template

maps to

Trello

Board Template (manual rebuild)

lossy
Fully supported

PlanZone reusable project templates define a starting structure of tasks and milestones. We export the template as a project skeleton and note which tasks are template-generated as a custom label (Template Origin) on each card. Trello has a Board Templates feature in the Premium tier for cloning a board structure. We do not create Trello Board Templates from PlanZone templates automatically; we deliver the template skeleton data and a written recommendation to use Trello's Board Templates feature to create the equivalent manually, which gives the admin control over which template becomes the canonical source.

PlanZone

Project Owner

maps to

Trello

Board Member (Admin role)

1:1
Fully supported

PlanZone records the project owner as a user reference. We map the project owner to the corresponding Trello workspace member and add them as an Admin on the destination board during creation. This preserves the ownership hierarchy so the original PlanZone project owner has board administration rights in Trello from day one.

PlanZone

File / Resource

maps to

Trello

Card Attachment (via Board resource link)

1:1
Fully supported

PlanZone stores project-level files and resources separately from task attachments. We export these as a file manifest listing each resource, its URL, and the project it belongs to. During the Trello load, we attach project-level files to the first card in the project's board (typically a board-intro or overview card) or add them as a pinned board resource if the destination uses a resource card pattern. The admin receives the file manifest as part of the scope agreement.

Pair-specific challenges

  • PlanZone has no public API; migration depends on CSV export quality

    PlanZone does not publish a public REST API. All migration work relies on manual CSV exports from the PlanZone UI. The fields and objects available are limited to what the export includes, which may not capture all custom fields, dependency chains, or historical comments. We request the customer to export all available data types (Projects, Tasks, Milestones, Attachments) from the PlanZone UI before migration scoping begins. Any data not present in the CSV export is flagged as a manual-recreate item in the scope agreement. This constraint is not pair-specific; it applies to every migration originating from PlanZone regardless of destination.

  • Trello Free tier caps workspaces at 10 Boards

    PlanZone customers with more than 10 active projects face a direct ceiling on the Trello Free tier. If the customer's PlanZone instance contains 11 or more projects, the destination workspace must be upgraded to Standard ($5/user/month) or higher before migration to allow all boards to be created. We surface this during scoping by counting distinct PlanZone projects in the CSV export. Skipping this check results in a migration that halts mid-load once the board count hits 10, requiring a workspace upgrade and a re-run.

  • Archived cards are not included in Trello JSON export by default

    Trello's native export (JSON) does not include archived cards unless they are manually restored to the active board before export. For migrations in the reverse direction (Trello → PlanZone) or for any customer who has archived PlanZone tasks they want to preserve, those records must be unarchived in PlanZone before the CSV export runs. We include an archived-record check as part of the pre-export preparation checklist and flag any archived records as requiring manual action if the customer wants them migrated.

  • Trello Custom Fields requires a Power-Up and Premium tier

    PlanZone custom fields map to Trello's Custom Fields Power-Up, which is a first-party Atlassian integration. However, Custom Fields is only available on Trello Premium ($10/user) and Enterprise ($17.50/user) tiers. If the destination workspace is on Free or Standard, we flag this as a tier gap during scoping. The admin must upgrade the workspace or accept that custom field data will be migrated as card labels or checklist items instead, which changes the filtering and reporting behavior.

  • Dependency links from PlanZone flat format require a conversion strategy decision

    PlanZone exports dependencies as a parent-reference field on the child task, a flat link rather than a structured relationship. Trello has no native dependency object, so the migration must decide between two strategies: creating card links using Trello's Card Links power-up (which draws a visual line between cards) or adding the parent task name as a checklist item on the child card. The choice affects visual clutter, the ability to filter by dependency, and how dependency chains render in Trello's board view. We validate the chosen strategy with the admin during the scoping call before the load phase begins.

Migration approach

Six steps for a successful PlanZone to Trello data migration

  1. Pre-export preparation and CSV audit

    We send the customer a pre-export checklist covering PlanZone Projects, Tasks, Milestones, Attachments, and Comments views. The customer performs the CSV exports from the PlanZone UI while we observe the field availability and flag any columns that appear truncated or missing. We audit the CSV column headers to discover custom fields, stage values, assignee patterns, and milestone flags. We count distinct projects and tasks to determine the target Trello workspace tier (Free vs Standard vs Premium). The output of this step is a CSV coverage report that defines the field window for migration and lists any gaps requiring manual handling.

  2. Dependency and milestone mapping design

    We design the transformation rules for PlanZone-specific constructs. This includes the dependency conversion strategy (card links vs checklist), the milestone mapping (card due date + label), and the stage-to-list mapping from PlanZone stage values to Trello list names. We also design the label color scheme for priority, milestone, and template-origin labels so the admin can filter across boards. The design document is shared with the customer for sign-off before any load work begins.

  3. Test migration and CSV coverage validation

    We run a test migration into a staging Trello workspace using the first project and a sample of 50-100 tasks from the CSV. This validates the list creation order, card creation, member assignment resolution, attachment upload, comment threading, and dependency link rendering. We reconcile the record count from the CSV against the created cards and flag any discrepancies. The customer reviews the staging workspace and approves the mapping before the production migration begins.

  4. Workspace tier and member provisioning

    We confirm the destination Trello workspace tier matches the project count. If more than 10 projects exist, the workspace must be on Standard or higher before we begin the load. We extract all distinct assignee emails from the CSV and match them against the workspace member list. Members without an existing Trello account are added to a provisioning queue for the admin to create before migration. Member provisioning must be complete before the load phase because Trello card member assignment requires an existing workspace user.

  5. Production migration in dependency order

    We run the production migration in record-creation order: boards first (one per PlanZone project), then lists (created per stage value within each board), then cards (one per PlanZone task with member assignment, due date, and labels applied), then attachments and comments as separate passes per card. Dependencies are re-linked after all cards exist so that the linked-card or checklist references are resolved correctly. We emit a per-board row-count reconciliation report after each pass so the admin can track progress and spot-check cards against the source CSV.

  6. Cutover, QA, and documentation handoff

    We freeze writes to PlanZone during cutover and run a final delta pass to capture any records modified during the migration window. We deliver a QA report comparing CSV record counts against Trello card counts per board, and a board-by-board walkthrough of 10 randomly sampled cards validated against the source data. We deliver the dependency mapping log, the attachment manifest, and a written inventory of PlanZone Templates and Workflows with recommendations for Trello Board Templates and Butler automations as replacements. We do not rebuild PlanZone automations as Butler flows; that work is handled by the customer's admin using our written inventory.

Strengths

  • Sovereign French cloud hosting satisfies local data-residency regulations for government and enterprise buyers.
  • Gantt-chart integration with dependency tracking gives visual project managers a clear timeline view.
  • Reusable templates accelerate setup for recurring project types common in industrial and public-sector contexts.
  • Collaborative web interface requires no desktop installation, simplifying deployment across distributed French teams.
  • Industry-vertical positioning for industrial projects, R&D tax credit tracking, and public policy work reduces configuration time for targeted use cases.

Weaknesses

  • Very limited public review volume makes it difficult to gauge real-world customer satisfaction at scale.
  • Pricing tiers are not publicly documented, requiring direct sales contact to evaluate cost.
  • No publicly documented API means migration requires either manual CSV export or a custom extraction effort.
  • The platform's French-language focus may create UX friction for non-French speakers in international organizations.
  • Small market footprint outside France means fewer third-party integrations and community resources compared to global PM platforms.

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 two and three weeks for accounts with fewer than 5 projects and 2,000 tasks, assuming the CSV export completes without field coverage issues. Migrations with more than 10 projects, cross-project dependencies, multiple custom fields, or that require Trello workspace tier upgrades move to five to eight weeks because of the multi-board sequencing, dependency graph reconstruction, and workspace configuration work. The CSV export preparation step on the customer side can add 3-5 business days to the timeline depending on how quickly the customer's PlanZone admin can run the exports.
