I'm probaby just missing something here, so forgive me, but ...

I want to upgrade to 2.2.3. I downloaded the upgrade version and was about to upload it to my server when I noticed that the configuration files were included. Won't this cause me to lose the connection to the database or any other changes I might have made?

Did you download the upgrade package? In the Upgrade package the config files are not included.

Yes, they are!

Okay, so, I just deleted the config files from that package and uploaded it to my server. However now iyt's not recognizing 2.2.3 as the new upgrade.

Yes the config files are there if you upgrade from an older version.

But if you follow the upgrade guide here...https://github.com/YAFNET/YAFNET/wiki/Upgrade-(from-Version-1.9.5.5-or-above) then you can see that you don't need to copy the folder to the server.

Did you copy the bin folder with all the dlls?

Okay, did that ... got an install screen with 2.2.3 listed. But ...

When I tried to do the upgrade it kicked back an error that you can see in that attached screenshot.

And when I tried to back out by restoring my backups, it gives me this error:

You also need to update the YAF.SampleWebApplication.dll

Okay, did that. Now it tries to do the update, but I still get the error I showed in the screenshot in my previous post.

Barring a solution here, is there anyway to get it not to default to the install screen?

Okay, I found a workaround that seemed to work. I went into the mssql/upgrade/constraints.sql file and commented out all of the functions that dealt with a TopicID constraint. The site is upgraded now, but does anyone have any idea how this may affect things in the future?
