Compilation error - After upgrading to Flexnet 2020 R2

[GopalRaghvani]

After I completed running PowerShell scripts to configure Flexnet 2020 R2

.\Config.ps1 "Config\FNMS Windows Authentication Config.xml" updateconfig

I got "HTTP Error 503. The service is unavailable."

I found the app pools for Flexnet were disabled. After starting the app pool I get Compilation error. I restarted the server and get the same error. I have logged a case, but need to get a fast resolution as Flexnet is unusable.

Error presented on browser:

Server Error in '/Suite' Application.

This error suggests that you are using a custom component delivered to you though a services engagement with Flexera or a Flexera partner that needs to be updated for compatibility with the new FlexNet Manager Suite release.

Take a look at the following thread for discussion on what to do here: FNMS GUI not working post upgrade to 2020 r2

Now I get the error:
Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.

Compiler Error Message: CS0101: The namespace '<global namespace>' already contains a definition for 'BusinessDataUploadsController'

Ignore this. I copied old version of BusinessDataUploadsController.cs into a backup folder. Once I renamed the .cs to .cs.backup it solved the issue.
