Simplex Migration

Migrate a 12.7 database simplex database to 16.0.

1. Migrating the Legacy Database
   Make sure that the database file is not in use, and run the iqunload utility with the -au (migrate database) and -c (connection parameters).
2. Verifying the Migrated Database
   To verify simplex migration, start the migrated database in read-only mode and perform post-migration tasks.
