First off, sorry if this has been answered previously. I did look and I couldn't find what I was looking for. So my problem is my old linux box running CentOS died, I do have a backup of the database. The issue i'm having is I decided to go virtual so I have a 2008r2 vm running a few sites. I decided to try 10.1.3 and thought I would be sneaky and just restore from the old backup. Good thing I created a backup of the default db, I get an error 500 when restoring on top of the new database. After a restore of the 10.1.3 data i'm at least able to bring up the newly installed mindtouch. I'm not sure what version I was using before and I would like to restore the old pages and data minus users if possible. I'm using MYSQL Administrator to do all the work. Does anyone know what tables I might need to restore? Maybe I need to run an upgrade script? Any help would be appreciated, this is for personal use and not commercial. So if nothing can be done then I can live with that.
