I am looking at upgrading an install from Moodle 2.5 to 2.7. Can anyone tell me if the upgrade makes changes to files in
The reason I ask is that I would like to do a trial upgrade on my test server. At the end I would have my existing database pointing to the 2.5 code base (no change) and another database that has been upgraded to 2.7 which points to a copy of the 2.7 code base. Both would point to the same dataroot files.
(This is all on test systems not live)
