1.  Any time you do a major system change, you need to perform a FULL backup.
2.  No, there should not be any issue.  IF the upgrade proceeds as an upgrade, it should be fine.

I assume it's Volume License... not sure the "M" though...

I don't see what can e the reason for doing this (OEM license can't be reused after). If we talking of a same version upgrade that will only change the licensing mechanism. Anyway that can be done using a key changer software.
If the server is DC I recommend to transfer all roles to another server, demote the server then upgrade.
Maybe a little more info can help us to beter help you.

Reason (maybe?):
He wants to virtualize the install.  Or migrate it to new hardware using tools like DoubleTake, Shadow Protect, or Acronis.

As has been suggested you will want to make sure you have a good backup.  There should however be no issues with upgrading from OEM to Volume License Media.  We do this all the time to allow imaging and virtualization of machines.  There will be no data loss, just make sure you launch the installation from within Windows so you can do the upgrade.  You will also want to make sure that your new installation media is at the same or higher level of service pack as the installed OEM system or you will encounter problems.  If you VLM media is a lower SP level, you can create a slipstream CD.

This slipstreaming article was written for XP but the steps are identical for Server 2003.  http://www.winsupersite.com/showcase/xpsp3_slipstream.asp
