Can I run different OS/Java/git versions in a Bitbucket cluster?

[John Lawlor]

I have a 3 node Bitbucket Data Centre Cluster. Over the coming months I would like to swap out the current nodes with newer nodes supporting later versions of git, java and a later OS version. I am going to switch from Centos 7.x to Centos 8.x.

My plan was to configure up the new node and add it to the existing cluster, then later hive off one of the older nodes. I would then continue until all nodes were up to the latest version.

I am just wondering if it's possible to have a node in the cluster which is running a later version of git, a different java version and a different os version?
