We are in the process of decommissioning the 11gR2 Oracle database that was replaced with the Oracle 12c database.
Data in the 11gR2 database was migrated forward to the 12c database so you should not see any issues with your existing maps.
Please check your existing maps (if necessary) to make sure they're connected to the 12C database.
The old database will be decommissioned by the end of the week.
