6.0 - upgrade existing 5.2 database from different serv er

Has anyone upgraded to 6.0 when 5.2 was on a different server? The upgrade
instructions for the 6.0 upgrade have a section on upgrading the existing
database, but it says "These instructions require that your server have both
5.2 and 6.0 installed on the same server before proceeding."

I have 5.2 on a different server. Do I have to re-install 5.2 on the new
server to upgrade my database, or does anybody know of another way to do it.
Unfortunately, there aren't any other instructions in the upgrade packet.
