Help with moving the database from CMS 1.7.6 to 1.7.7?

I have 2 CMS servers up and running both are Win 2008 r2 one is CMS 1.7.6 and the other is the new 1.7.7.
I tried to upgrade the 1.7.6 per the instructions but couldn’t get it to work. So I created a clean install of the 1.7.7 CMS.
Can anyone give me some advise on moving the database from the old server to the new server?
Or is this even possible after the 1.7.7 CMS has already been fully installed?

Moving the old database to the new would be the equivalent of starting an upgrade as it is the database that needs upgrading.

Your previous ticket about databases did have an answer after some other comments (Upgrading from Xibo 1.7.4 to 1.7.7) did none of those help you?
