Upgrade from 3.4.5 to 3.4.13
I have zk cluster with 3.4.5 version and planing to upgrade to 3.4.13
version, can some one point me to a upgrade steps? When i copy snapshot
from 3.4.5 node to 3.4.13 node it seems to be working but not sure what is
the proper way of upgrading existing cluster.
Thanks,
Ram

A rolling restart is enough. Just stop one server ,replace jar, restart,
and it will join back the quorum. Then do this for the rest of the servers.
Update requires a restart, but you can save yourself a full restart this
way. You will have no downtime.

Norbert,
Thank you, do we need to restart process after jar replacement?

Hi,
We had a discussion about this not long ago, it was 3.4.8 to 3.4.13, but
same things have to be done in this case.

If you just replace the jar, you don't even have to copy anything else.

Norbert
