Move AOT objects to another model

If we move AOT objects from one model to another model in the same layer than can it cause any issues?

Can it change object id’s?

I would like to move our CUS Model and VAR model objects to CompanyCUS and CompanyVAR model respectively.

If you merely select the objects inside AX and send them to another model in the same layer, they’ll keep the same IDs and everything. If you exported them, deleted them from one model and imported to another model, they would get new IDs. You usually shouldn’t care about IDs in development environments anyway, but it depends on your deployment processes.
