I would suggest making backups of the portals (dbs included) and testing them one by one for upgrade issues, setup a copy of the portals, copy all of the DNN2 files into these duplicated portals, modify the web.configs, and then access the site, see if everything correctly loads. Do this on a test site, as to not break your existing applications.
It should work. I didn't lose any of my design issues. Only thing I had to worry about (I think) was the custom modules...have not upgraded my production yet, just done some testing.
I just tried to upgrade, and it did not go well.
I copied all of the files in, changed the Web.cfg file and the project file to point to the correct Virtual Directory.
I lost all of my Tabs and users. I restored the DB, but it did not make any difference.
Anyone know what I did wrong?
I just restored all of the files and the DB and I am back up on 1.10
I am stupid also.
You have to change the default provider in the Web.config file to point to SQL..........
It created an Access DB and kept looking at it.
I guess I should have read the other forums first.
