Migrating Issue Links Viewer
Our app (Issue Links Viewer) is a static integration that doesn’t affect created issues and does not store any data.
If you migrate from Server (Data Center) to Cloud, just install the app; it works out of the box.
The only difference in Jira Cloud is related to the fact that there are 2 issue views available. In the new view, the app needs to be ‘activated’ on that view per user.
