Upgrading the Database from Oracle 11g to Oracle 12c

Hi, I have a system developed on Mendix 4.7.2 and connected to Oracle 11g Database. If I upgrade the Database to Oracle 12c , will there be any issues??? will the data be affected, like losing data... etc? will there be any special things that i have to do?

Oracle 12c is a supported database: https://docs.mendix.com/refguide/system-requirements#server

Normally upgrading an Oracle database does not affect the data, but check with your DBA. Also, make sure you have a database backup.

One thing to keep in mind is that Mendix 4.7.2 is an old version (no longer supported). You may need to upgrade to mendix 6 or 7, as this includes updated oracle jdbc libraries which may be needed for oracle 12.
