The following chapters in this manual describe Adaptive Server 15.0 upgrade issues:
Migrating to Adaptive Server 15.0 requires you to review your current applications and system administration procedures for any changes that could cause system problems or unexpected processing results.
This is the most time-consuming part of migration preparation; choose a method to do this that suits your needs and resources. Possible choices include:
Writing your own scripts to examine and change applications.
Running the reserved word check for the 15.0 server and using some of the tools available such as the stored procedures sp_checkreswords and sp_procqmode. See the Reference Manual: Procedures for information about these stored procedures.
Using the preupgrade utility to check for common upgrade problems. See the Utility Guide for more information.
