backup and restore exchange to same volume

Hi,

I have a single server exchange 2010 running on windows server 2008 r2.  I have decided to re-configure the disk array on this system, which will require me to backup and restore exchange.  Here is the current configuration:

Current:

Array 1 is a Raid 1 with 2 disks and has a single volume C: with the OS + Mailbox db's + logs
Array 2 is a Raid 5 with 4 disks and has a single volume D: with Exchange related files and folders (size >2TB)

Future:

Array 1 will stay as is (raid 1 on 2 disks)
Array 2 will become a Raid 1 with 2 disks and house a single volume D: with Exchange + logs
Array 3 will become a Raid 1 with 2 disks and house a single volume F: with Mailbox db's

so my question is:

Can I simply do this:

1. Backup all exchange related folders (inetpub, Program Files\Microsoft Exchange) from D: onto an external drive
2. Build arrays 2 and 3 with drives D: and F:
3. Restore the exchange related folders from step 1 back onto D:
4. Reboot the server and everything will work? :)

Any suggestions?

thanks!
