The following instructions are for migrations of Jira to a different server. See Upgrades and migrations within same server instructions for in-place upgrades or migrations.
Before you migrate
We recommend Jira admins to upgrade to the latest version of Git Integration app from the Atlassian Marketplace.
Run the instance for some time (a few days or weeks) and once the testing is stable – then do the migration.
Upgrade/migrate
Follow the standard instructions from Atlassian on migrating to another server (select your Jira version).
No extra steps are required.
After you migrate
Verify that configured integrations and repositories in the Manage Git repositories screen are correct and index properly.
