How to move EPDM vault from test server to new server and rename?

Yep, just follow the instructions in the guide.  I am actually going throug a similar process - splitting a single EPDM server into two, and doing the upgrade as well.  Only, I'm taking the chicken route to ensure it is done correctly - I'm hiring my VAR to do it .  But, I did go through the procedures to understand what it entails, and to ensure an old test server wasn't overlapping with a new server.

Wayne,

If you are moving to a live server and the data you currently have in the vault is obsolete or invalid, you are better off exporting the test vault settings into a cex file by right clicking on the test vault name, from the administration console and selecting "export". Then do a fresh install on the live server and create a new vault with the new name and import the cex file. This way your database isn't full of the useless test data and you don't need to hack and slash at the settings just to do a name change. Once your new vault is setup and you've imported the settings, start adding in the live data.

As far as upgrading goes, you should definitately follow the upgrade instructions from the Installation Guide.
