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 SP200 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 SP200.

Mixed-Version Environments

For Replication Server 15.7.1 SP200 and later, mixed-version environments containing versions earlier than 12.6 are not supported. You can upgrade directly to Replication Server 15.7.1 SP200 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 SP200, the replicate Replication Server must be version 15.7.1 SP200 or later.

SQL Anywhere Version for ERSSD

ERSSD requires SQL Anywhere. SAP Replication Server 15.7.1 SP200 includes SQL Anywhere version 16.0 on these UNIX platforms: 64-bit Linux, Solaris SPARC, Solaris x64, HP-UX Itanium, and IBM AIX. The ERSSD and sample Replication Server, and the ASA16 directory are not available for the 64-bit Linux on POWER (IBM pSeries) platform.

Version 15.7.1 SP200 also includes SQL Anywhere version 12 for upgrading an ERSSD database format if you have installed an earlier version of SQL Anywhere.
