I've upgraded my DNN-installation in three steps from 5.6.3 to 7.0.6.
The process included some errors, but I don't know if I should worry about this:
Upgrading from 5.6.3 to 5.6.8 gave me some Telerik errors, like:
00:00:10.749 - Installing Package File Telerik_06.00.00_Install: Error!
However, the upgraded website loaded correctly, so I went on with my (test)process.
Upgrading from 5.6.8 to 6.2.6 gave me no error-messages, but the website did not load. It gave an error-message about Telerik:
telerik.web.ui.webresource.axd' is missing in web.config
UpHowever, when I changed the application pool from v2.0 to ASP.Net 4.0 Classic, it díd work. (I got this fix from this site)
Upgrading from 6.2.6 to 7.0.5 gave me no errors.
So, although I have quite a few layout-problems, my website is working.
I now doubt if I should still worry about the Telerik-error-messages, as I didn't understand what was wrong, I just used the first fix that Google gave me. And I even ignored the error-messages from the first upgrade.
Should I be more careful in my upgrade-process, or is the end result as OK as I would want it to be?
