Migrating Oracle Database from 12g to 19c

Hi,

I am currently using Appian 22.1.875 on Linux servers. Presently, my applications are using Oracle12, but now my DBA team is planning to migrate to 19c. Will there be any issues after the upgradation of DB to 19c? Has anyone tried this? Was there any impact on the existing applications in Production environment because of this migration?

Please help.

Regards,

Chetana
