Besides the volume ID and status "Migrated", what other values might get returned by IBM z/OS MVS FTP server, in column "Volume" (default DATASETMODE directory listing format)?
For example:
Volume Unit Referred Ext Used Recfm Lrecl BlkSz Dsorg Dsname
Migrated F010317A.FD2F
SS1010 3390 2017/05/31 1 1 FB 309 27810 PS F010917A.FSSP
Looking at this with an eye toward parsing directory listing results in an FTP client.
