Yes perfectly acceptable to have a mix of versions in a clustet .

As you are aware ESXi 4.1 can only host version 4.0 and 7.0 VMs.

5.1 can host 4.0, 7.0 8.0 and 9.0 so be careful with vMotions

Will it cause any damae to the VM or it will not vmotion?

If you try to vMotion an unsupported VM, it will fail validation, and not move the VM.


ESXi 5.1 - VM versions 4, 7, 8, 9
ESXi 4.1 - VM versions 4, 7
