Going "P" to "V"

Greetings all,

We have @ 50 virtual servers and another 50 or so physical servers.  The guy I manage,  who does most of our VMware tasks, has done quite a few P to V's...but we have not had to do a P to V yet for a physical server that is connected to my CX4-120.  All previous P to V's have been stand alone servers that are NOT attached to our SAN.  All these host servers connected to my SAN are running Windows Server 2003, and have EMC software like Replication Manager, Power Path, Navishphere (CLI), ADMsnap etc. installed.

I read that VMware uses Raw Device Mapping so that the new virtual server will still have its "LUNs" presented to it when it's no longer a physical server connected via fiber to the SAN.  What about the other EMC related products like Replication Manager, power path, Navi etc?  I still need to be able to take "snap shots" of the LUNs on my host servers vis my Replication Manager server.  All of these snap shots then get presented to a server that is attached to a tape library where I perform my nightly backups., using Legato's Networker.  Or does moving all my Physical servers to Virtuals mean VCB to back the new virtual servers up?

I need to make sure I understand what I am embarking on as we begin to transition all our Physical servers attached to our SAN to Virtual servers.

Is my question making sense?  Perhaps when you do the step of P to V'ing, I'm hoping RM, PowerPath, Navi et. al get copied over to the new virtual and that someone responds to this post and tells me it's simple.  There is a side of me that is fearful in the sense that going P to V for servers attached to the SAN will be difficult to transition over.

Any information that can be passed along to me regarding converting a physical server that has it's data on the SAN to a virtual server is greatly appreciated.

Thanks,

Jon
