Currently, there are no automatic steps to migrate from Jira Server + Data Center to Jira Cloud. We will evaluate Atlassian’s self-managed Jira to Jira Cloud migration tool when it is released later in 2020.
Indexing Jira issues via commit messages is the same in Jira Server + Data Center as Jira Cloud. All the associations will be preserved.
At this time, manual commit <--> Jira issue associations cannot be migrated automatically but request BigBrassBand Support for instructions on how to check.
We highly recommend testing your Jira migration to the Cloud on a test Jira Cloud site. AC-1528 is a bug in Atlassian Jira Cloud that breaks all Jira Cloud Atlassian Marketplace apps when a new project import is made. When migrating your users to Jira Cloud – we recommend installing and configuring the Git Integration for Jira Cloud app after all of your Jira users/projects/issues data is imported and verified.
