Hi

I have an installation of DNN V4.3.x on Windows Server 2003 (not live as yet). I need to upgrade it to the latest version 4.8.4 however the documentation only seems to cover V3 to V4 etc.

So, I unzip the downloaded _install.zip file into the site directory and then copy back my web.config (or modify the connection settings for the new web.config file).

When I then access the site it starts a new install and consequently goes wrong.

I know it's probably something sooo... simple but what am I doing wrong?

Many thanks

Hello Mike, thanks for the response.

I have done a bit more work on the problem and in doing so I have accidentally made things worse! So, this is the current status:-

Main web folder: Now running 4.8.4 with a clean database. Installed fine and the new module I wanted to run works fine (this was the initial reason to upgrade from 4.3.4)

Copy of original web folder: I accidentally unzipped 4.8.4 here so my original "virgin" copy is a bit messed up.

Database: Original 4.3.4 database intact and backed up. Created new database for clean 4.8.4 install.

If I copy the backup folder (the original web folder as mentioned above) to the main website folder and then unzip the original 4.3.4 DNN and point at the original database then I get a problem as follows:

(NOTE: After unzipping I modify web.config to set SiteSqlServer (2 versiona), machinekey and InstallationDate)

When I originally unzipped 4.8.4 into the 4.3.4 website folder, DNN started to run an install but encountered an error (no details displayed in the progess list box) and then got into an endless loop scrolling messages which were something like "Undefined: Success" ad infinitum.

I guess what I really need to try and achieve now is to revert the whole thing back to 4.3.4 (i.e. resolve the above error) and then understand better how I should progress moving it to 4.8.4.

Any help is much appreciated.
