Comparing Db2 LUW objects to DB2 on z/OS


I’m in the process of looking for software that will compare the database on my Db2 instance running on AIX to my Db2 subsystem running on the mainframe (z/OS).  I’ve heard good things about this product:

I know structures such as a tablespace on the mainframe is different then a tablespace on a Db2 AIX instance.  Can you tell me this tool supports both platforms for Db2? 

Thanks, Tom
