Downgrade of Adaptive Server

You can downgrade Adaptive Server to an earlier version while there still are transaction records related to SQL statement replication in the log.

If you downgrade to a version earlier than 15.0.2 ESD #3, SAP recommends that you use the standard documented procedure to downgrade an Adaptive Server with replicated databases. This procedure includes draining the transaction log. See the Adaptive Server Enterprise 15.0.3 Installation Guide.

Adaptive Server 15.0.3 provides the following downgrade support for Replication Agents version 15.0.2 ESD #3 and later:

Replication Agents continue to replicate data even if the log contains information for SQL statement replication.
When a Replication Agent reads a transaction containing SQL statement replication, it sends atomic modifications for that statement and ignores information related to SQL statement replication.
