Cluster Upgrade - Version Mix

Jump to solution

Just to make my life easy.....

Is it possible to upgrade a cluster one host at a time 3.0.2 to 3.5 ; therefore have a temporary mix of host versions in a single cluster? Or do I have to upgrade, create new cluster, and relocate the guests to the new cluster?

hi,

It shoud be fine, as you will need to upgrade the VC first which in theory be backwards compatible.

Follow the upgrade guide http://vmware.com/pdf/vi3_35/esx_3/r35/vi3_35_25_upgrade_guide.pdf

If you wanted to be extra careful, I would suggest just disabling HA.

Good Luck
