Quick Migration

The following is assumed for the Quick Migration conversion strategy:

There is plenty of additional DASD space and that the existing static cache volumes can be kept as is. You will use other DASD volumes for the dynamic cache.
There are relatively few SVTS subsystems running. If necessary, you accept short periods of down time during which no Virtual Devices are available.
All the subsystems will be converted at once.
Because the existing static cache linear data sets will remain available, you can fall back to static mode quickly if necessary. Once you are sure that the Dynamic Cache Management is stable, you can delete the static cache linear data sets and reclaim that space.
