We have upgraded Solman 7.1 to 7.2. We have an existing ARIS database in version 9.8.8. We want to synchronize ARIS with the fresh Solution Manager instance. Back in the beginning of our project, ARIS was established first and then Solman so the sync was done. I am not sure how they did that as I was not there at the time. We have transferred the project to ARIS from Solman already but we are getting an error when we try and synchronize all of the models back to Solution Manager.

It says "You have more than one rootnode for your process step library. Please check your branch model for a unique rootnode."

I have not been able to find anything on what this actually means or how to fix it. Any ideas?
