Our customer is now about to perform an upgrade to Oracle Server 12c in the production environment .

Virtually all applications accessing the server are using Oracle Client 11g.

In the testing environment, where the upgrade was performed last year, this Oracle Client 11g is still used and without problems.

What we would like to know is if the use of Oracle Client 11g against Oracle Server 12c is officially certified by Oracle, because otherwise

all the applications would have to be re-tested for Oracle Client 12c.

Howdy, Stranger!
