I am trying to compare 2 physical data models in IDA v8.5 and get the following error message:
Models with different root objects are not supported.
Only versions of the same model can be compared.
If you are comparing files under SCM control, the models must have a common ancestor.
If you are comparing files outside of an SCM system, each model being compared must have been created by modifying a copy of the same original file.
Creating a new model file and copying information in from the original model is not a methodology supported by the comparison technology.
I get the error whether the models are in the same project or not. Can someone help me to resolve this ?
Thank you in advance!
