You can transfer existing definitions for backup media from the media definition file control.med(database version 6.2) to the new media definition file dbm.mmm (as of database version 7.2.4.2).
The media definition from the old file is not transferred if there is an identical media name in the old and new media definition files.
The old definitions for backup media do not contain entries on the relevant backup type for a particular medium. We therefore recommend that as soon as you have transferred a media definition in this way, you use the DBM command medium_put to define the backup type. Otherwise you will have specify this explicitly when you start the backup procedure on this medium.
