While the process of converting a PDS to a PDSE is indeed trivial, what happens after may not be so. I know my CIO would want assurances that this process would not disrupt our business at all.

About ten years ago we added "DSNTYPE(LIBRARY)" to IGDSMSxx. It's amazing how many issues, albeit small ones, that created--even in our little shop.
There are a surprising number of PDS usage scenarios that work differently (or not at all) with PDSE. I guarantee that some adjustments will need to be made. Now and then DSNTYPE=PDS needs to be added to some JCL to work around such an issue. Things are a bit tougher with DYNALLOC scenarios...
