Need Advice on Upgrading Exchange 2003 Standard to Exchange 2003 Enterprise w/Clustering

I have called M$ on this issue, but wanted to make sure if anyone else here had done this before or not, and what to look out for.  I have a very simple Exchange setup.  I am running 2003 w/SP2 applied on an old Dell 6650.  Windows 2003 Standard w/SP2 is the OS that I am running on.  OWA runs on the same box and not a front-end server.

Fours years later, I now wish to do the following:
1) Upgrade the site to Exchange 2003 Enterprise with a two-node cluster.  I am thinking I can do this, by introducing a new exchange server into the existing site running Exchange Enterprise and Windows 2003 Enterprise server.  I can then make the new server the site master and setup the clustering accordingly.  After that, all I should have to do is to pull the mailboxes over to the new server.
2) Establish a front-end server for OWA services.  I am thinkg that I can set the current Exchange Server running standard edition as a front-end server (after I move the mailboxes to the Enterprise server of course).  

M$ said that I should be able to accomplish what I want by the aforementioned plan, but I wanted run it by the experts on this site in case I am missing something.  I just can't believe it going to be this straight-forward.

Thanks

That is pretty much all there is to it.
Build the new cluster, then treat it as a regular Exchange server with doing the move mailbox etc. You will need to strip all mailboxes off the standard server, which means looking for those accounts that have mailboxes that were never used.

Key point is to ensure that the backend servers (cluster) are fully up to date on patches before you introduce the frontend - this means ensuring the patch level on the frontend is the same or higher as the backend. If the existing server has been fully maintained with updates (not just service packs) then this shouldn't be an issue.
