Yes, that is why I asked about vCenter.

I would suggest the same approach, move vm's off of one host, remove it from the cluster, shutdown, zone in new storage and boot off of new LUN, rebuild, join to cluster, and migrate vm's, and then repeat with other hosts. It's a long-winded process, but it would be safer, and will give you a chance to upgrade/update if you haven't had a chance to do that yet.

Your SAN team should be able to help you with this if they have the ability to do snapshots at the SAN level. I am in the middle of the same thing except I have too many LUN's and VM's for snapshots, so I have to do cold migrations for the VM's and all my boot LUN's I am just re-installing the ESX OS on the new SAN.

Hope this helps!

Since they are different vendors, replication won't get you there the easy way.

It will be easier to build a new ESX server booting from the IBM, and then migrate the virtual machines.

Do you have virtual center or are you using stand-alone ESX environment? VC will make things easier if you have it.

I´m ussing VC, i migrated allVM to the new DataStore without problem.

I have a Cluster with 7 ESX, i think the best way will install new ESX, shutdown one ESX of Cluster and include the new ESX on HA.

What do you think???

Thanks for response

Hi, if you get issues with replication of the ESX boot partitions then take a look at thisthread on restoring ESX configuration http://communities.vmware.com/message/1133079#1133079
