integrations with crucible/fisheye

[mcote]

• We are doing Jira server to Cloud migration. After the migration is completed to Jira Cloud, can we integrate Jira Cloud & Fisheye and crucible ( Server ) with the application link?

• Do we need to upgrade Fisheye and crucible ( Server ) to be compatible with Jira cloud latest version to integrate with Jira Cloud? and  *Will the application links be migrated automatically during the migration or do we need to re-create the link one by one for each record?*
