You can use Replication Server version 15.0 or later with different versions of Adaptive Server. Although you can use data sources and destinations other than Adaptive Server, Replication Server requires Adaptive Server for warm standby databases and either Adaptive Server or SQL Anywhere for Replication Server System Databases (RSSD).
Sybase does not support replication of Adaptive Server system databases, such as tempdb, model, sybsystemprocs, sybsecurity, and sybsystemdb. The replication of the Adaptive Server system database master is supported only if the Adaptive Server supports master database replication.
Some capabilities of Replication Server version 15.0.1 require you to use an Adaptive Server version 15.0.1 or later.
Some capabilities of Replication Server version 15.2 require you to use an Adaptive Server version 15.0.3 or later. For example, the SQL statement replication feature in Replication Server version 15.2 requires Adaptive Server version 15.0.3 or later.
Refer to the installation and configuration guides and the release bulletin for your platform for more information about using Adaptive Server with Replication Server.
