Using FDRPAS or TDMF to go from smaller volumes to larger volumes will take you only so far. You can move one MOD3 to one MOD9 (or MOD whatever). After that you have to move datasets. I know there is another FDR product that will help move datasets, but even that has limitations. Naturally you could use SMS to help by disabling new allocations to the MOD3 and over time things may move as datasets are reallocated. At some point you will have to have subsystems down (or lpars down) to move datasets.
As we have swapped out DASD subsystems we have gone through the pain of eliminating as many MOD3 volumes as we could. There came a point when we had to get business unit approval to take things like CICS or DB2 or IMS or MQ or even whole lpars down to move datasets. Thanks..

What Skip should do is upgrade from whatever ancient DASD configuration has been carried forward at SCE for decades to modern, 21st-century DASD geometries. FDRPAS and similar products will help him do that seamlessly. Even being past the half-way point on UCB count won't be an issue if he consolidates his mod-3 DASD pools to mod-27s, which are nine times larger. Even an extremely-conservative conversion to (still quite ancient) mod-9s can cut the device address footprint by 2/3! -- Phoenix Software International Edward E.
