Due to the upgrade to Java 8 in OpenEdge 11.7, support for SSLv3 and other cipher suites (MD5 and RC5, for example) has been retired. Instead, support for TLS has been updated and replaces those retired technologies.
Nothing need be done to re-configure instances for TLS after completing an OpenEdge 11.7 and the instance migration described in
Migrating existing PAS for OpenEdge instances. However, if you must revert to those retired technologies, you cannot use OpenEdge 11.7 or later releases.
