What is Cloud-hosted migration assistant?
The Cloud-hosted migration assistant is Atlassian’s new tool for migrating Data Center instances to Atlassian cloud.
It allows you to copy data from your Data Center instance to a migration environment hosted on Atlassian cloud and run the migration to your cloud site from the new location. Additionally, it enables on-demand transfer of changes in your Data Center data from the migration environment to your cloud site.
The Cloud-hosted migration assistant is currently available only to a limited number of customers participating in an early access program. We are not enrolling new customers at this time, but we will keep you updated when we reopen enrollment.
How is the Cloud-hosted migration assistant different?
Here’s how the Cloud-hosted migration assistant differs from the Jira Cloud Migration Assistant:
Avoid creating manual infrastructure: Atlassian provides a migration environment hosted on the cloud. This saves you the effort of setting up or maintaining a separate staging environment.
Lightweight on your Data Center: The Migration Connector app continuously streams data from the Data Center to the cloud with minimal impact on your production environment, keeping it up to date. You can test and validate migrations multiple times without impacting your Data Center instance, thereby avoiding the risks and delays associated with a single migration event.
Automated and scalable: The migration environment can be provisioned, reset, or reloaded on demand, supporting migrations of any scale.
App migration support: The Cloud-hosted migration assistant supports migration for the same apps as JCMA.
Minimised downtime: With incremental migrations, only the most recent changes are migrated since the last migration, which significantly reduces downtime.
How can you use the Cloud-hosted migration assistant to migrate data?
Here's how you can migrate data using the Cloud-hosted migration assistant:
Install the required apps on your Data Center instance
You will need to install the Migration Connector app and the Cloud Companion app from Atlassian Marketplace. These apps will help connect your Data Center instance to a migration environment hosted on Atlassian cloud.
Set up and connect your cloud and Data Center instances
In preparation for migration, connect your DC instance to your cloud instance. Read how to set up Data Center and cloud instances
Once the Migration Connector app is set up and the DC and cloud instances are connected, we’ll create a migration environment to temporarily host your data. The migration environment is designed to facilitate the transfer of data from Data Center to cloud, and you will not have access to this environment.
Set up your database
You’ll need to set up a database for migration. Configuring your database helps the Migration connector app receive database change events. Read how to set up a database
Copy your data
Use the Migration Connector app to copy your data, such as projects, attachments, and supported third-party Marketplace app data, into the migration environment. Atlassian will copy your Data Center data here and perform a full migration to your cloud test site environment. Read how to copy data
Run your migrations
Perform your own test and production migrations to your target Jira Cloud site. During this time, users can keep working in Data Center while the migration environment is kept up to date with ongoing changes. Read how to create a migration plan
Migrate data incrementally
Run incremental migrations to transfer only the changes made since the previous migration.
Validate and run the final production migration
After testing, you can initiate the final production migration and switch your users to the cloud site with minimal downtime. Your Data Center instance is temporarily set to read-only during this step to ensure data consistency.
