How to Migrate Your Team’s Tasks Between Task Managers: Step-by-Step Checklist + Mapping Template

Overview

A task manager migration has three separate goals: preserve important information, reproduce the team’s working process, and give people a clear cutover point. Treating it as a simple copy-and-paste exercise can leave behind context or create inconsistent records that are difficult to repair later.

Before selecting an export method, define what “successful” means. For a small workspace, that might mean every active task, assignee, due date, label, and attachment appears in the new system. For a larger project management setup, success may also include completed work, comments, subtasks, dependencies, recurring tasks, custom fields, and links to supporting documents.

Use this task manager migration checklist as a repeatable project:

1. Inventory: list workspaces, projects, boards, databases, users, automations, integrations, and archived information.
2. Classify: decide what to migrate, what to archive separately, and what can be deleted after approval.
3. Map: match each source field to a destination field before importing anything.
4. Test: migrate a representative sample rather than the entire workspace first.
5. Verify: compare records, permissions, dates, attachments, and workflow behavior.
6. Cut over: freeze changes in the old system, complete the final export, and direct the team to one source of truth.

Keep a copy of the original export and a dated migration log. If an import behaves unexpectedly, these records give you a reference point for troubleshooting and recovery.

Checklist by scenario

Scenario 1: Moving between similar task managers

When both systems use projects, lists, tasks, statuses, and assignees, the migration may be relatively direct. It still requires field decisions because similar labels do not always mean the same thing.

• Export all active projects and a defined period of completed work.
• Record the source workspace structure: team, project, list, section, task, and subtask.
• Match source statuses to destination statuses. For example, “Review” may need to become “In progress” or a custom workflow stage.
• Confirm that user accounts exist in the destination before assigning tasks.
• Check whether due dates include time zones or time-of-day values.
• Test labels, priorities, dependencies, recurring tasks, and custom fields separately.
• Verify that task URLs, comments, and attachments remain accessible after import.

If you are planning to migrate Trello to Asana, for example, do not assume that cards, lists, and boards will automatically become the exact structure you want. Decide in advance whether boards become projects, lists become sections, labels become tags, and card members become assignees. Write these decisions into the mapping sheet before using a connector or CSV import.

Scenario 2: Moving from a document or database workspace

Notion-style workspaces and other flexible databases often combine tasks with meeting notes, briefs, specifications, and reference material. The main risk is importing the visible task rows while losing the surrounding context.

• Separate actionable tasks from reference pages, notes, and historical records.
• Identify relation fields such as project, client, product area, or parent task.
• Preserve source-page links in a dedicated “Original link” field when possible.
• Export long-form comments and page content separately if the destination does not support equivalent notes.
• Decide whether checklists become subtasks, task descriptions, or a separate project-planning template.
• Review formulas, rollups, views, and filters manually; these often do not transfer as ordinary task fields.

For critical work, keep the original workspace available in read-only form until the team has confirmed that the new task manager contains enough context to operate without it.

Scenario 3: Consolidating several tools into one

Consolidation is an opportunity to simplify, but it also creates competing naming conventions and duplicate records. Create a source column in your mapping template and assign each imported record a source identifier.

• Choose one destination naming convention for projects, statuses, priorities, and labels.
• Identify duplicate tasks by title, project, owner, and due date rather than title alone.
• Choose a system of record for comments and attachments when two tools contain different versions.
• Archive low-value historical records instead of filling the active workspace with them.
• Publish a short guide explaining where new tasks, requests, and updates should go after cutover.

Scenario 4: A small team or solo operator migration

For a freelancer or small business, a full historical migration may not be worth the time. A practical approach is to move active work, recurring responsibilities, current client information, and a useful archive. Preserve older records through an export or read-only backup rather than rebuilding every completed task.

Use the migration to review your daily planner workflow, time blocks, and project stages. Remove fields nobody uses and keep only the information needed to decide what happens next.

Export, import, and field-mapping template

Create a simple mapping table before touching the live workspace. The table below can be copied into a spreadsheet and expanded for your tools.

Export a small test set containing simple tasks, subtasks, completed work, attachments, comments, custom fields, and unusual dates. A good test set represents the exceptions, not only the easiest records. Do not begin the full import until the team has reviewed the sample and approved the field mapping.

What to double-check after import

Use a post-migration verification checklist with both a technical reviewer and an everyday user. Confirm the following:

• Count: compare source and destination counts for active, completed, and archived tasks.
• Ownership: sample tasks owned by every team member and confirm assignments survived.
• Dates: inspect overdue, future, recurring, and time-specific tasks.
• Relationships: test subtasks, dependencies, linked projects, and parent-child records.
• History: open representative comments and verify that important decisions remain understandable.
• Files: open attachments using the permissions of ordinary team members, not only an administrator account.
• Views: check saved filters, calendars, dashboards, and workload views.
• Automations: review rules, notifications, recurring task behavior, and external integrations before enabling them broadly.
• Permissions: confirm that private projects, client information, and internal notes have the intended visibility.
• Links: test links in meeting notes, weekly status reports, SOPs, and other documents that point to migrated tasks.

Ask one or two users to complete a normal workflow from start to finish: create a task, assign it, add a comment, attach a file, change its status, and close it. This practical test often reveals problems that row counts cannot.

Common mistakes

• Importing everything: Historical clutter makes the new system harder to use. Define an archive boundary before migration.
• Skipping the test import: A full import can multiply a small mapping error across thousands of records.
• Assuming names are equivalent: “Priority,” “importance,” and “impact” may represent different decisions. Document the intended meaning.
• Ignoring permissions: Imported files or comments may have different visibility in the destination.
• Leaving two systems active: Parallel updates create conflicting versions. Set a clear freeze and cutover time.
• Forgetting automations: Recreated rules can send duplicate messages, assign incorrect owners, or create unwanted tasks.
• Failing to communicate the change: A new task manager needs a short operating guide, not just an invitation email.
• Deleting the source too soon: Retain the export and old workspace until verification, training, and any agreed retention period are complete.

When to revisit

Revisit this checklist whenever your team changes task management tools, adds a new integration, restructures projects, or prepares for a seasonal planning cycle. Tool providers can change export formats, import limits, connectors, field support, and automation behavior, so confirm the current instructions before relying on an older procedure.

It is also useful to run a lighter version of the checklist during quarterly workspace cleanups. Review unused fields, duplicate projects, inactive users, outdated automations, broken links, and the boundary between active work and archive. If the same workaround appears repeatedly, update your mapping template and team SOP rather than relying on individual memory.

Before your next migration, assign an owner, choose a backup location, set a freeze window, and schedule a verification session. Then copy the mapping table, add the source and destination tools, test a representative sample, and obtain approval before the final import. That preparation turns a disruptive system change into a controlled project with a clear finish line.
