I am currently migrating Exchange 2007 on W2003 (also a DC)to W2008R2 on a vm.
I wont go into the politics of why I cant go straight to Exchange 2010 or 2013  -long story.
Ill explain the set up before I ask any questions.
Current Exchange 2007 sits on a physical W2003 64 bit with the information stores on our Netapp.
I have installed a W2008R2  VM with Exchange 2007 on it, AD has synced over what it needs.
On the new server I have installed Snapdrive , Snap Manager for Exchange and single mailbox recovery , the same as the old Exchange Server.
Im not that savvy with esxi at the moment I need to do some training so I apologize if I ask redundant or silly questions.

What are the steps I should take from here in regards to pointing Exchange at the Information datastores on the LUNS.
I would like to just test with the IT department first.
Can 2 Exchange Servers share the luns? Or do I need to unmount from one first?
I realise I then need to demote the DC side of things and then uninstall the old Exchange.

Any help is much appreciated !!!

You cannot just point the new Exchange server at the old databases. Even if you could, I wouldn't want to.
Ignore the fact that it is a SAN - create new storage and disks and do a straight migration, which means new databases and move the mailboxes. Zero risk and zero downtime.

Once you have migrated all mailboxes and public folders, remove Exchange 2007 with add/remove programs. DO NOT TOUCH DC FUNCTIONALITY UNTIL THAT IS COMPLETE. It is not supported to run DCPROMO on a machine with Exchange installed.
