I would also say that the OS is not the most important step in this, although your mileage may vary when considering mainframes or even the various open systems. A host based solution like Double-Take could for example be of use, but this only supports Windows and Linux systems.
But for me there is a much more important question. Is this something you want to do online or do you have the option of doing this offline? If you can perform this thing offline, is there a limit to the downtime? How long do you want to use the arrays in parallel? Do you even have the option to install an appliance for just this task, or have you thought about an array virtualization controller?
If you can give us a bit more background info, I'm sure we can give you some guidance on what you could do with the available EMC technology, or perhaps give you some pointers on alternatives that may also work.
1. Create new LUNs on V-MAX identical to LUNs on HP
2. Create a copy of LUNs from HP to V-Max by Open Replicator
3. Plan downtime.
During downtime:
4. Stop the application.
5. Export and/or unmount all related filesystems.
6. Delete/Pause Open Replicator session
7. Remove zones from SAN to HP add zones to V-MAX
8. Maks devices from V-MAX to the host
9. Discover new LUNs by host
10. Import and/or mount all filesystem in needed order
11. Start application.
You can use PowerPath Migration Enabler to avoid downtime. In this option you can create LUNs on V-MAX, assign it to the host, start Open Replicator session with control by PowerPath migration Enabler and the transparently move data from "old" LUNs to new ones.

EMC Open Replicator for Symmetrix creates remote point-in-time copies. You may verify the compatibility before starting the migration.
