In Sybase IQ 12.6, you can deploy new releases on one server of an existing multiplex without interrupting other servers. The write server must be the last node updated to version 12.6.
New 12.6 features are only completely available after
all servers are upgraded to 12.6.
Sybase IQ 12.5 and Sybase IQ 12.6 require different versions of the IQ plug-in, the IQ Agent, the Sybase Central Toolkit, and the Java Runtime Environment. For related information, see “Controlling IQ Agent port number”.
For upgrade instructions and supported components, see Sybase IQ Installation and Configuration Guide.
