Problem in Module Builder after upgrade

I recently started to get back to an older project, and went through the upgrade process to tie the site into NuGet instead of doing the manual process.  Well this upgraded the site from 7.1.5200 to 8.0.5719.0 which seems to have broken my custom modules that I had in place.  The error message I'm getting in the backend is:

This seems to be happening in the log file right after this:

 and yes, the homerotator_banner is one of my custom module controls and it is tied to dynamic content.

It looks like I could modify the database to kill the Foreign Key, but what damage will that do to the system?  What other options do I have?  Should I upgrade to a different version first and then move to 8.0?

 Thanks!

Hello George,

Can you try to restore locally your 7.1 project and upgrade it using the Project manager following that article:
http://docs.sitefinity.com/upgrade

In case this do not helps I would recommend you to open a support ticket in order to inspect the project more detailed.

Regards,
Svetoslav Manchev

That did it - thanks.
