Upgrading Cloverleaf on a Cluster

Hi,

Not sure whether this is the correct area but I’m sure somebody will move it if it isn’t.

We have Cloverleaf 5.3 running on a Windows 2000 2 node cluster. If I upgrade it to 5.5 what steps/precautions will I need to take to ensure no interruption to the service? The cluster is active/passive with each server having its own local OS and Cloverleaf and the Quorum on shared disks – all mirrored.

Has anybody got experience of this?

Thanks in advance

Garry
