Are you asking what the considerations are for migrating from Syncsort (Syncsort Inc's sort product) to DFSORT (IBM's sort product)?
We've spent considerable time over the years making such a migration easier and many customers have successfully done such a migration. If you send me a note offline (email@example.com), I will send you some documents prepared by the DFSORT Team that discuss this. Please put "DFSORT" somewhere in your Subject line to catch my attention.
If that's not what you're asking, then you need to state more clearly exactly what it is you want information on.
