[Upgrade Issue] 10.1 to 11.1 Caching Implementation Memory Cache issue

Hello,

I am following this tutorial to upgrade my Telligent 10.1 UAT instance to 11.1. 

https://community.telligent.com/community/11/w/user-documentation/63024/how-do-i-upgrade-telligent-community#Upgrade_Website

I have replaced

  • migrated the filestorage
  • updated the database
  • moved my connection and config files to the new Web directory
  • removed the files in the jobs server folder and socket bus folder
  • copied in the new files in the jobs server and socket bus folder

However, when launching the web page, I received this error:

Server Error in '/' Application.

Here is the full stack trace:

I have tried

  • Removing all plugins
  • Using the default Web.config
  • Verifying the Application pool properties

Any feedback would be helpful
