When converting ZMF library types from PDS to PDSE format, the staging dataset definitions need to be changed in ZMF ISPF Option A.A.2 (and A.G.2 if the change is for all applications). However, customers should also keep this consistent and change all promotion, baseline and production libraries to PDSE format at the same time, too, if they have not already done so. If these promotion, baseline and production datasets cannot be changed at the same time, then they should be changed BEFORE making the change to the ZMF staging library type definition.

For an example of the type of problem that failure to do this can cause, and for additional information, see the following KB article: KM000006993.
