Greetings everyone,
We are facing an issue with a dependency on a managed solution on our own software, where one of our developers exported components of our own solution from UAT environment (Managed) and inported to DEV (unmanaged). Several months later and several solutions on top of it, when trying to repackage our repackage our solution to clean up UAT and PROD, we noticed the dependency.
Now when trying to import to a client environment, it always says that it has dependency on the "Imported Solution" (Managed). See ilustration below:

Can anyone advise how to address this problem? This was several months back, and recreating everything that was built is almost impossible and would cause errors in production.
Appreciate any help or guidance you can provide.
Thanks,
PC
