so do i need to add something to my config to define Version or is it framework.php?

In OC-2.2, at least, a typical (root) config.php PATH content would usually look like this and also contains additional DB Fields: But other than that, it may not be as easy as you figured, in the first place, trying to UPGRADE a basically
un-upgradable 1.5.6.x Version and it's DB, therefore, other problems possibly still exist, besides of the config.php content.
Good Luck!
