need some pointers on this. i installed p3 on a separate folder on the webserver, but using the same database, to test it out. It works ok. However, since I have done quite a few modifications on the p2.1 (tips obtained from this forum) i wanted to use it. So how do i switch back i.e. i did try to just re-use the p2.1 folder, but the images are in chaos -- what changes are made in the database during p3 upgrade (that i need to downgrade -- damn, no db backup) ? thanks.
