Adaptive Server version 12.5.x introduces support for wider columns, more columns, a larger number of user logins, and multiple logical page sizes. To support these extended limits, there have been several changes to existing system catalogs.
The catalog upgrade in 12.5.x may affect your existing application. If you are upgrading from pre-12.5, see What’s New in Sybase Adaptive Server 12.5.1? for a complete list of catalogs that are affected by the relaxed server limits.
