Paul, It is not the DSORG that has to support Extended Format, it is the ACCESS METHOD. The DSORG defines and extended format dataset, but the Access Method has to support IO to it.
As far as I know QSAM and BSAM are the only Access Methods that support PS-E. Before converting to PS-E on a large scale you need to check for datasets that are being accessed by other Access Methods. You can find this in the Type 14 and 15 SMF records. If you have MXG this is a relatively simple exercise - sometimes the harder part is incorporating the results into your ACS logic. Also be aware that some utilities like DFSORT and SYNCSORT will automatically detect PS-E and use BSAM to process the files in place of EXCP. You don't have to exclude datasets just because you sort them.
