You can format your dasd on most dasd subsystems to FBA.  That addresses most 
of the problem.
However, VSAM still has a concept with FBA of Min-CA and Max-CA.  That is the 
conversion headache when migrating from one FBA device type to another.

I would first check to see if your current dasd subsystem can be formatted to 
emulate FBA.
Second, see what FBA device types your dasd subsystem can emulate.

If it can emulate the same min-CA/max-CA as a 9345, very easy conversion.

In either way, a FBA to CKD(3390) conversion would be near the bottom on my 
list.

G'day Listers,

We have VM Magic from SDI running on an old system which we 
wish to upgrade but VM Magic does not run in 64 bit mode.

VM Magic is being used to emulate 9345 dasd. There are 
applications that have device type coded in programs which 
would make conversion to 3390 difficult.

Does the list have any suggestions on what we can do ?

Thanks in advance
Graeme Moss
