Support for version 8 and earlier databases   When using Sybase Central, Interactive SQL, or the SQL Anywhere Console utility, databases created with versions of the software older than SQL Anywhere 8.0.0 are no longer supported. This includes databases that were created with older software and then upgraded using newer software. Attempting to load such databases will result in an error on database startup. You can connect to these databases from Sybase Central to unload them into a new version 10 database. See SQL Anywhere Server upgrades.

jConnect version 5.5 and 6.0.5 supported   SQL Anywhere now supports jConnect versions 5.5 and 6.0.5 (version 5.5 was supported in 9.0.2) for connecting to the database server. jConnect is available as a separate download from  http://www.sybase.com/products/informationmanagement/softwaredeveloperkit/jconnect. Consult the jConnect documentation for information about its supported features.

Processor requirements on Intel x86 architectures   On Intel x86 architectures, SQL Anywhere supports only Pentium-class and newer processors, and will not start on older processors, such as the 80386 or 80486.
