How do you plan on moving these patients over? If ClinicOffice notices duplicate patient codes within the same Clinic, it will offer to assign a new one when you try to save that patient record. If you are wanted to merge the 2 Clinics together in that same database then this is the process you would need to follow.
There is the option to allocate unique patient codes globally, however this can’t be done retrospectively.
