EVC mode

[khaliqamar]

hello,

I am having one cluster ( A ) with 3.5 ESX. which I want to migrate to my new cluster ( B)  ESXi 4.1.

Is there any way to migrate the VMs without down time ? 

Both clusters ESX/ESXi hosts are with different CPU but same vender. So i cant migrate without EVC mode.

to enable EVC mode I still need to power off all VMs on my old 3.5 cluster (A) ?

Is there any way i can migrate VMs without downtime.

Thanks in Advance

You'd best enable EVC on the old cluster, even if this means a whole shutdown. It should make your migration simpeler. If you don't mind me asking, why is the new cluster vSphere 4 and not 5?

My virtual center is 4 and at this point it is not possible to update my Virtual center and i don't want to run 3 different versions in my virtual environment. so that is the only reason i am running 4 not 5

So there is no other way for me to do without downtime ?

even if I migrate with EVC mode on I still have to upgrade the virtual hardware and tools etc.

Thanks again

The only other option is to use VMware Converter and V2V the vms - the downtime will be limited

I think there is no way we can turn on EVC without powering off the VMs.

There is no way to enable EVC mode and migrate the VM without shutdown the VMs.
