My latest idea is to install 1.3 into a moode13 folder on the same machine and also create a moodle121 folder into which I'll move all the 121 files and folders. Then I'll move the 1.3 files and folders up to root and run 13 using the same database and private data folders (after it updates the database).
This should work as long as the database for 1.3 builds on version 1.21 and is NOT different. This way I could easily swap out one version for the other if I have problems and need to revert down to 1.21.
Is this going to work or is the 1.3 database a whole new structure?
