VMFS2 & VMFS3 Problem

Hi,

I have 2 servers,

One which is running ESX 2.5.2 and has many VM's.

The other server is running ESX 3.0 Beta R2 ( New Install, nothing inside )

Both server are connected to my EMC Storage ( Connected to same LUN )

All my ESX 2.5.2 VM is place inside this LUN

How do I Migrate the VM's from my 2.5.2 server into the new 3.0 server?

I am facing the VMFS2 & VMFS3 imcompatible problem. where i cannot see the LUN in ESX 2.5.2 if i format my LUN to VMFS3 where this is needed for ESX 3 beta R2.

But if i format it to VMFS2, then there will be a problem for me to create a new VM in ESX 3, where ESX3 need a VMFS3 Partition.

Did any one here facing the same problem ? Please help me !

Thank you !

You cannot have ESX 2 and 3 on the same LUN.

ESX 2 can only work with VMFS-2

ESX 3 works with VMFS-3 and can only read VMFS-2

So you should have 2 LUN's and migrate your machines from 2 -> 3
