I have never Storage vMotion a vCenter appliance. Is it as reliable as Storage vMotion any other VM? For example my nervousness stems from this is the appliance that is controlling the operation, and if there is any pause or latency in the Storage vMotion, it may fail and then I am in trouble.
I am also performing this on the cluster that this vCenter manages. It is the vCenter that manages our management cluster of all other vCenters.
The good news is the SAN storage is very fast and reliable. It is a medium build appliance so almost 1TB of disk.
I have vMotion this appliance many times in the management cluster is manages for hypervisor upgrades, no issues. I have just never done a Storage vMotion.
We take a VAMI backup every morning as well.
