You can use Replication Server version 12.5 with different versions of Adaptive Server and SQL Server. Although you can use data sources and destinations other than Adaptive Server, Replication Server requires Adaptive Server or SQL Server for warm standby databases and for Replication Server System Databases (RSSDs).
Some capabilities of Replication Server version 12.5 require you to use an Adaptive Server version 12.5 or later.
If you are using SQL Server version 11.0.x or earlier, you must use an LTM program for SQL Server instead of a RepAgent thread, and you cannot use schema replication in a warm standby application.
For more information about RepAgent, see Chapter 5, “Setting Up and Managing RepAgent.” For details about LTM software, see Also refer to the installation and configuration guides and the release bulletin for your platform for more information about using Adaptive Server with Replication Server.
