Is it mandatory to setup Cluster when upgrading License from Confluence 6.15.6 Server to Datacenter?

[Manas Mathur]

Currently no clustering is setup in Confluence 6.15.6 Server. We now want to upgrade License to Confluence Datacenter but don't want to setup clustering.

-Is it possible to do that and how?

-If yes than can we still setup Clustering in future?

Hi @Manas Mathur , 

since Confluence 7.2, to migrate to Data Center you only need to change your license (System Configuration -> License Details). I think this is the easiest way since you would only need to update Confluence.

Otherwise, with the 6.15 version, you'll have to follow this guide to setup a load balancer and shared file system : https://confluence.atlassian.com/doc/migrate-from-server-to-data-center-203651.html

Let me know if this helps,
