Avoiding potential migration problems

Sybase IQ 15.2 no longer supports some 12.x features and objects. You must correct these items before you migrate your databases. “Addressing unsupported objects” tells you how to identify and update unsupported objects and metadata. “Correcting invalid SQL syntax” identifies syntax changes you must make before migration.

NoteDuring migration, the 15.x server creates a message file (*.iqmsg.R) as it reloads the generated schema. This file is normally deleted as part of a cleanup operation for successful migrations. If the migration fails during the reload stage, cleanup does not occur, and *.iqmsg.R remains in the unload directory. *.iqmsg.R may contain information that can help solve your migration problems.
