BW (Oracle 12.1c) and ECC (Oracle 19c) | Oracle compatibility of ECC 7.0 and BW 7.0

Hi SAP,

Good day!

We will be upgrading System1 (ECC NW 7.0) database from Oracle 11g to Oracle 19c.
And System2 (BW NW 7.0) that is connected to System1 will be in Oracle 12.1c.

Can you please advise if there will be an impact between the two systems (ie process, chain, RSA1 connections, reporting, jobs) if they are on different Oracle versions?

Regards,
