Best Practices for Upgrading a Cluster?

Hello!

Thank you for reaching out. Yes, you can avoid downtime while performing patches/upgrades in a cluster. This is one of our biggest upsides when it comes to clustered environments.

To do this, each instance will have to be brought down individually, while the other(s) remain active. While the instance is down, apply any patches or upgrades, then restart services. Once the server is back up and running, repeat the process for each server until they are all patched/upgraded.

Hope this helps!
