Hello @eg1995
Apologies for delay in response to your query. Much appreciate your patience in this matter.
We can comment on license mobility for Microsoft licenses only (Windows, SQL, etc.). For third party applications like Oracle, you will need to confirm with them whether licenses are mobile or whether additional licenses must be procured. I recommend doing a DR drill in test environment regardless of what Oracle states, just to be sure that the application will run in the DR region post failover.
