Run select @@version.
The server should now be at version 15.7.
In Adaptive Server version 15.7, several changes have
been made to the system stored procedures and many new error messages
have been added. After performing a binary overlay, you must perform
the postinstallation tasks before running installmaster or instmsgs.ebf.
Once the
server has been brought up on the new binary and and you have completed the
upgrade of system tables, shut down then restart Adaptive Server. This prevents
incorrect table statistics from being stored in memory, and which may lead to
poorly optimized query plans.
