In order to efficiently migrate Jira Server projects to another Jira System running on DataCenter, I need to use a plugin that is only available in Jira DataCenter (because they have stopped selling plugins for Jira Server).
But if I upgrade Jira Server to Jira DataCenter on the original system, will all the links to Confluence Server, Crowd Server and Bitbucket Server still persist? e.g. if a Jira ticket was referenced in Confluence before Jira was upgraded to Data Center, will it still be referenced? Will Crowd still authenticate access to the upgraded Jira? Will I still be able to access code changed under a Jira ticket by clicking through to bitbucket?
