Below are guidelines for installing version 15.0 of Open Server on the same server with other Sybase products:
On the Windows platform, installing Open Server 12.5.1 on the same server as Adaptive Server 12.5.0.3 causes Adaptive Server to fail to start. To configure this combination, either upgrade Adaptive Server to 15.0, or follow the directions in the SDK and Open Server 15.0 Installation Guide for Microsoft Windows.
In general, Sybase recommends that you place new installation of Open Server in separate directories from other Sybase products, such as Replication Server, OpenSwitch, Enterprise Connect™ Data Access, and Sybase IQ, unless Sybase Tech Support has specifically recommended installation in the same directory to address an issue.
On the Windows platform, use .bat files to ensure that each product is started with the correct environment variables and version of Open Server.
Sybase does not recommend mixing versions of SDK and Open Server in the same directory. For example, do not install SDK 15.0 in a directory containing Open Server 12.5.1—in this case, upgrade both SDK and Open Server to 15.0.
