**Protect your task context during migration.** Learn what Microsoft Planner silently drops (dependencies, checklists, attachments), how to restructure flat buckets into a working hierarchy, and run a parallel cutover so your team keeps moving while you switch tools.
Ryan Mitchell10 September 202610 min read1,223 viewsTL;DR: Most migration guides tell you what to export from Microsoft Planner. This one shows IT company owners exactly what gets silently dropped in transit, how to remap flat buckets to a structured workspace without losing task relationships, and how to run a parallel cutover that keeps your team working while the switch happens.
Planner's native Excel export gives you a workable starting point, but it's incomplete in ways that will cost you if you don't account for them before you move anything.
What exports cleanly: task names, assigned members, due dates, bucket names, completion status, and priority labels. These fields come through consistently in the .xlsx file Planner generates today.
What gets silently dropped:
Task descriptions and notes (the actual context behind a task)
Checklist items within a task
Attachments and file links
Comment threads and activity history
Recurring task settings
Dependencies between tasks
That last one matters most for IT teams. A deployment task that blocks three others looks identical to a standalone task in the export. The dependency is gone, and nothing flags it as missing.
Before you run any Microsoft Planner export, do a manual audit of your highest-stakes boards. Open each task that has a checklist, a comment thread, or a file attachment and copy that content somewhere durable, a shared doc, a notes field in your destination tool, anywhere. This is the core of any honest project migration checklist: protect what the export file won't carry.
Once you know what's preserved and what isn't, you can organize and visualize your migrated project tasks in a way that actually reflects how your team works.
Planner's bucket system is a kanban board, nothing more. Each bucket is a flat list of cards with no native parent-child relationship, no section hierarchy, and no way to express that a task belongs to a phase, which belongs to a project, which belongs to a program.
When you migrate projects from Microsoft Planner into a unified workspace for IT teams, that flat structure collides with a hierarchy that expects projects, sections, tasks, and subtasks to be distinct, nested objects. Planner buckets map loosely to sections, but they carry none of the metadata a section holds: no owner, no date range, no completion percentage.
The result is predictable. A direct export drops every task into a single flat layer. Relationships between tasks disappear. Progress roll-ups break because there is nothing to roll up to. A 40-task board that felt organized in Planner becomes an unstructured list in the destination tool.
Converting Planner buckets to a task hierarchy is not a formatting problem. It is a structural redesign problem. You need to decide, before migrating, which buckets become sections, which become sub-projects, and which are just labels that should be replaced with tags.
Once you have that map, you can organize and visualize your migrated project tasks without rebuilding context from scratch.
Before you touch the export button, you need three things: a field map, a pre-migration audit, and a validation checklist. Without all three, you will finish the migration and spend the next week hunting down tasks that lost their assignees, due dates, or notes in transit.
Part 1: Data mapping matrix (Planner fields → Taro)
Microsoft Planner's native Excel export includes task name, bucket name, assigned to, start date, due date, completion percentage, and notes. It does not export checklist items, label colors, or attachments. Map each exported field to its Taro equivalent before you move a single row.
Planner field | Taro equivalent | Notes |
|---|---|---|
Bucket name | Section | One bucket = one section inside the project |
Task name | Task title | Direct carry-over |
Assigned to | Assignee | Confirm user accounts exist first |
Due date | Due date | Verify timezone alignment |
Notes | Task description | Plain text only; formatting may strip |
Checklist items | Subtasks | Must be recreated manually post-import |
Labels | Custom fields | Map color labels to named field values |
Checklist items are the most common silent data loss in any Microsoft Planner export. Recreating them as Taro subtasks or milestones (epics) preserves the step-level detail that bucket views never showed.
Part 2: Pre-migration audit template
Run this before export:
List every active board and count open tasks per board. Boards with fewer than 10 open tasks can often be archived rather than migrated.
Identify tasks with no assignee, no due date, or no description. Decide: clean them up in Planner now, or flag them for post-migration triage.
Screenshot or export checklist items separately. These will not survive the standard export.
Confirm every team member has a Taro account and their email matches the Planner "assigned to" field exactly.
Part 3: Post-migration validation framework
After import, check these before you close Planner:
Task count matches between the export file and the destination project
All subtasks (formerly checklist items) are attached to the correct parent task
Due dates render correctly, especially for tasks that crossed a month boundary in the original board
At least one team member spot-checks five random tasks against the original Planner board
Once validation passes, you are ready to organize and visualize your migrated project tasks in a way Planner's flat board view never supported.
The Microsoft Planner export is a starting point, not a complete handoff. When you export a board to Excel, you get task names, bucket names, assigned users, due dates, and completion status. What you don't get: task notes, checklist items, attachments, and any custom labels your team built over time. Plan for that gap before you touch a single record.
Here's the process that preserves the most context:
Export from Planner. Open each plan, go to the three-dot menu, and select "Export plan to Excel." Run this for every active board. If you have more than a handful of plans, do this on the same day to avoid drift between export timestamps.
Audit the gaps immediately. Open each spreadsheet and flag every task that has notes or attachments in Planner. These won't appear in the file. For a mid-size IT team running 10 to 50 users, you'll typically find that a meaningful share of tasks carry context that lives only in the notes field — that's the data your project data cutover strategy needs to account for explicitly.
Map buckets to your destination hierarchy. Planner buckets are flat. Most destination workspaces use folders, sections, or sprint columns. Decide before import whether each bucket becomes a section, a tag, or a separate project. Inconsistent mapping here is the most common source of lost task context.
Rebuild stripped fields manually or via API. For task notes, copy them before cutover. If your destination tool has an API, a simple script can push notes from a staging spreadsheet into the correct task records after import.
Run a parallel period. Keep Planner read-only for five to seven business days after import. Teams catch missing context faster when they can compare both workspaces side by side.
Once tasks are in, organize and visualize your migrated project tasks in a unified workspace for IT teams so ownership and timelines are visible to everyone from day one.
Permissions are the part of a team permissions migration that most checklists skip entirely, and they're the most likely cause of a day-one lockout.
Start by auditing your current Planner board membership before you touch the destination workspace. Export the member list alongside your task data and map each person's Planner role (owner, member, or read-only) to the equivalent role in your new environment. These rarely map one-to-one, so do this manually.
Set up the destination workspace's permission structure before migrating a single task. If access isn't confirmed before cutover, team members land in a workspace where they can see tasks but can't edit them, or can't see them at all.
The recommended order:
Recreate all project spaces and boards in the destination tool
Assign admin and owner roles first
Add contributors and members next
Confirm read-only or guest access last, especially for external stakeholders
Keep your project migration checklist updated as each role is confirmed. Don't mark a board "migrated" until access is verified by the person, not just assigned by you.
Once permissions are stable, you can organize and visualize your migrated project tasks without worrying that someone is working from a locked or outdated view.
Run both platforms in parallel for a defined window — two weeks works for most IT teams — before you cut over completely. During that window, new tasks go into the new workspace only. Planner becomes read-only reference. This single rule prevents the most common failure: team members updating tasks in the wrong system the day after launch.
Set your hard cutover date before the parallel run starts, not after. Announce it in writing with the exact date, what changes, and what stays accessible. Vague timelines create the confusion you're trying to avoid.
For a unified workspace for IT teams, the parallel run also gives you a live validation window. You can confirm that task dependencies, assignees, and attachments transferred correctly before Planner is fully retired.
Your project data cutover strategy should include three checkpoints: mid-parallel-run (day 7), one day before cutover, and 48 hours after. Each checkpoint answers one question: are team members working in the right system?
Three mistakes account for most failed Planner migrations.
Migrating the most complex project first. Teams pick their flagship project to "test" the new tool. That's backwards. Start with a low-stakes, recently completed project where the task context is already settled. Validate your process before you touch live work.
Skipping the Microsoft Planner export review. Planner's native Excel export omits checklist items, comments, and attachment metadata. If your project migration checklist doesn't account for those gaps before cutover, that context disappears permanently.
Ending the parallel run too early. The previous section covered running both platforms simultaneously for a defined window. Most teams cut it short under pressure. Dependencies surface late, and there's no fallback.
If you're still deciding what kind of tool you're migrating to, task apps and project management tools solve different problems — worth confirming before you commit.
The migration itself is straightforward once you know what Planner won't carry. The real work is the audit: identifying tasks with notes, checklists, and attachments before you export, mapping your bucket structure to a proper hierarchy, and running a parallel period so your team can catch gaps while both systems are still live. Download the Microsoft Planner-to-Taro Migration Checklist to lock in your data map and validation steps, then set up a Taro workspace so you can run the import against a live destination and see exactly how your tasks land before you fully commit.
Map Planner's flat buckets to a proper hierarchy: decide which buckets become sections, which become sub-projects, and which become tags. Then rebuild stripped fields like task notes and checklists manually or via API before your team starts working in the new tool.
Use sections and subtasks to create the parent-child relationships Planner's flat buckets lack. Assign owners to sections, set date ranges, and track completion rollups so progress is visible across projects, not just within a single board.
Exports include task names, bucket names, assignees, due dates, completion status, and notes. Missing: checklist items, attachments, file links, comment threads, recurring settings, and task dependencies—the context that usually lives in notes or comments.
Create a data mapping matrix before import that assigns each Planner bucket to a destination section or project, and each field (assigned to, due date, notes) to its equivalent in the new tool. Inconsistent mapping is the most common source of lost context.
Compare task counts between the export file and the destination, spot-check five random tasks against the original board, confirm due dates rendered correctly, and verify all subtasks are attached to the right parent before closing Planner.
Keep Planner read-only for five to seven business days after import. Run both systems in parallel so your team can catch missing context and validate that tasks, dates, and assignees transferred correctly before you fully switch over.
