We have to move and split an existing ESXi cluster. Currently it is a 7-host cluster, which will be split into a 5-host non-production cluster and a 2-host production cluster.
Currently all backups are provided through the use of a single Veeam server pointing to this 7-host cluster.
I'd like to know the following (assumptions of mine are in brackets):
1. What are the implications for Veeam when migrating the VMs to the new clusters? (I'd assume that we would just point Veeam to the new VC which in turn would allow it to see the new split clusters);
2. When we split manufacturing servers onto the production cluster, we would have to redo the backup jobs and settings. Veeam would not reference the old backups anymore, correct? We would then let the backups run for the set retention period, after which Veeam would expire the older backup sets of these VMs;
3. For the VMs that are left on the non-production cluster, would we be able to modify the backup jobs to include the remaining VMs on the 5-host cluster and then continue backups to the same directory etc. as per normal?
If I haven't explained it better, please let me know. Ideally we are trying to make this as pain-free as possible.
