I've seen other responses to your question but most of them are simply 
rubbish.

You can FTP or SNADS a save file from any version of OS/400 to any 
other system (as long as you do a binary transfer). There is nothing 
special about a save file until it contains data thus CRTSAVF on any 
version of OS/400 creates the same kind of object. What determines 
whether a save file is usable on a given release is the SAVxxx command 
which sets various values indicating the format of the save file 
contents (note that: the CONTENTS, not the save file object itself).

So you can FTP save files from 530 back to 450 with impunity. You will 
not be able to restore from those save files **ON** 450 but you don't 
want to do that anyway. You will be able to FTP the save files from 450 
back to 530 and restore their contents. The only proviso is that you 
have a working 530 system to which to send them.
