Hi Mollie;

  You cannot undo a PB App's migrated source code once the IDE migrates it.

   Hopefully, you either have a full back-up of the App's source code in the previous PB release OR a complete back-up from your SCM system of the previous App's PB Version source code.

Reports, i.e. dws, are the exception to this rule.

Sometimes they will simply recompile under the original version of the code using the original IDE.
Other times you simple go into the header and change the version from (as an exmaple) 19 to 16, then recompile.

In either case you need to have the original version of the IDE.

As this question is about InfoMaker, I don't remember if IM offers an edit source or import export option. Maybe someone that has IM installed can answer that. If those options aren't available, then I guess this can be complex (you may need powerbuilder in equivalent versions of im you are using).

Andreas.
