Running iqunload in schema unload mode (iqunload -n) lets you connect to an existing IQ 12.x server, and generate a reload.sql script that contains the entire schema for your 12.x database. You can run this script against a new Sybase IQ 15.1 database to recreate the schema of the legacy database. Running iqunload in schema unload mode provides two major benefits. You can:
Verify the correctness of the schema by applying it to a new Sybase IQ 15.1 database.
Estimate how long the actual migration process should take.
Schema unload mode is not supported for Sybase IQ 12.6.
You must use Sybase IQ 12.7 ESD 5 or later
to use this option.
