    Hi,

    So I have a webserver that I haven't touched in a couple years and I'd like to get it current.  It's on v. 09.02.00 (366) (Windows server 2012).

    I downloaded 9.4.1_upgrade.zip and failed miserably so I've rolled it back.

    Looking for hints or someone who's more up to date on this than I am... do I need to do any pre-requisites or upgrade the DB ahead of time?

    I tried to do an in-place upgrade like I have in the past - should I have done a side-by-side instead?

    Thanks,

    Steve

        I didn't check that.  Thanks for the tip!  I'll let you know if that fixes it.

          Well that didn't solve it - I still get a Server Error as soon as the new files are loaded:

          Server Error in '/' Application ... Runtime Error: An application error occurred at the server. 

          On the localhost it's Server Error in '/' Application - An unhandled exception occurred during the execution of the current web request.  Details: Syste.IO.FileLoadException:  Could not load file of assembly 'Microsoft.Extensions.DependencyInjection.Abstactions' or one of its dependencies.  The located assembly's manifest definition does not match the assembly reference.

          I saw this article: https://dnncommunity.org/...s/aft/312 which pointed me to read the error a little more carefully and it listed a specific file (in this case Microsoft.Extensions.DependencyInjection) so based on the article above I commented out the line in web.config which included that reference and then I was able to complete the upgrade.

          Thanks again for pointing me in the right direction!  Hopefully this helps someone else.
