Atlassian has announced the Server EOS in many places and prominently. There are still about two years until the final shutdown date. This gives you the chance to evaluate your options early on.

It's a good thing that Atlassian is currently offering a free trial year for all Server and Data Center customers who have more than 60 days of active maintenance remaining. This offer is only valid within the period from Feb. 15 to May 15, 2022, and as long as you accept the offer within this time frame, you will receive free access to the Atlassian Cloud for 12 months. An ideal opportunity to familiarize yourself with the features in the cloud, create a proof of concept and test a migration!
