What is Confluence Cloud Migration Assistant?

Confluence Cloud Migration Assistant is an Atlassian app created to help with migrations from Server or Data Center to Cloud. Although data migration is its primary functionality, it comes together with a number of assessments and checks that make sure your data can be migrated.

The assistant provides the following functionality:

  • Assess and prepare Marketplace apps

  • Review and trust email domains

  • Migrate data or users

  • Pre-migration checks that show issues with your data or the migration itself

We take privacy seriously and only store migration data for 14 days from the day a migration is created.

The assistant is pre-installed in newer Confluence versions and available on Marketplace for earlier versions.

The assessments available in the migration assistant are a great way to prepare your data for the move.

Assess and prepare Marketplace apps

You most likely have at least one Marketplace app. If you ever upgraded Confluence, you know that apps can be challenging and it’s not different with migrations. The assistant helps you migrate your apps to Cloud.

Review and trust email domains

The assistant requires that you mark your domains as trusted or not. We’ll migrate only users from your trusted domains.

Where to start with data migration?

When migrating Confluence, you choose what to migrate by building a migration plan and filling it in with data. You can migrate everything at once or divide it into many migration plans.
