We bought new license for our SAP ECC6.0 and I need to know the following.
1. Is it possible to use the same old user ids (consultants,coreusers,developers) in all instance with the new license?
2. Is it possible to migrate all my old license users to new license, so that I don't have to generate any fresh access keys or face access key issue with different installation number?
3. Is there any prerequisite or post test after new license update to check that there is no discrepancies?
