Requirements for Upgrading

There are several requirements for the site, route, and system versions, mixed-version environments, and different platforms, when you upgrade Replication Server.

Site, Route, and System Version

If a replication system domain has Replication Server 15.7.1 SP100 and later, then the system version and route versions in the replication system domain must be version 12.6 and later.

If the Replication Server version, the site version, and the route version are earlier than 12.6, you must upgrade Replication Server to version 12.6 or later, set site version to 12.6 or later, and upgrade routes to 12.6 or later, before you can install Replication Server 15.7.1 SP100.

Mixed-Version Environments

For Replication Server 15.7.1 SP100 and later , mixed-version environments containing versions earlier than 12.6 are not supported. You can upgrade directly to Replication Server 15.7.1 SP100 from versions 12.6 and later, including any ESDs for versions 12.6 and later.

Note: To create a database subscription from a primary Replication Server with version 15.7.1 SP100, the replicate Replication Server must be version 15.7.1 SP100 or later.

SQL Anywhere Version for ERSSD

ERSSD requires Sybase SQL Anywhere. SQL Anywhere version 12 included with Replication Server 15.7.1 SP100, is available on 32-bit and 64-bit Windows platforms.
