During migration, the 15.x server creates a message file (*.iqmsgR) as it reloads the generated schema. This file is normally deleted as part of a clean-up operation for successful migrations. If the migration fails during the reload stage, clean-up does not occur, and *.iqmsgR remains in unload directory. *.iqmsgR may contain information that can help solve your migration problems.
See “Migrating Data” in the Sybase IQ Installation and Configuration Guide for more information.
