Can an Oracle 19c database dblink to an Oracle 10.2.3 database


I have an Oracle database that dblinks to an Oracle database.
I am upgrading the Oracle database to 19c (

Will my dblinks to the Oracle database continue to work?

Based on this document from Oracle Support, the answer appears to be "No". A 19c client (the owner of your DB Link) is only supported/compatible with a server version of 11.2 or greater.

Conversely, a 10.2 database can only support a client as new as 12.1, so any upgrade of your 12.1 database to any newer version will break your db link.
