If you install iSeries Navigator (at least a database component), you can expand the required schema (or schemas) and select the option βGenerate SQLβ for various types of objects that SQL recognizes. Then SQL can be ported to any DBMS that you will use.
Of course, this is separate from any data. And there is a significant chance that many objects will not make any sense for any other platform. There is little chance that the "database" will not make much sense on another platform. This will depend on how long the database has existed (it may precede SQL), how progressive the developers have been over the years, how many advantages they have had for the platform functions, etc.
