How to compare the same layer in 2 geodatabases

[JoseSanchez]

Hello everyone,

I have the same layer in 2 different geodatabases and both layers have a different number of records.

I am looking for a way to compare both feature classes and find the records that are different between them to siolate them and add them to the one that has less records.

How can I do that?

Jose, Data Interoperability extension has a ChangeDetector transformer that will find unchanged, added and deleted features, or alternatively an UpdateDetector transofmer that will find unchanged added, deleted and updated records.  UpdateDetector requires a shared primary key.
