Hello

There are two netbackup master servers in our environment. One is with 6.5.3 referrred as old master server and another one is with 7.6.0.1 referred as new master server.

We have recently migrated from old master server  to new master server.  We have about 30 tapes that need to be migrated into the new catalog ( 30 tapeswhich were used in the old master server

May I  know the steps that need to be followed?
