Backup exec restores support in Netbackup

We have just migrated to Netbackup from Backup Exec . However we still have a large number of tapes stored away in backup exec format which will need restoring from in Netbackup .

We have developed a process to import Backup exec Media in Netbackup with the help of the link below

However i understand Backup exec restores will not be supported in the next major Netbackup  version release . If this is the case we will have to import ALL our backup exec tapes now which will be a nightmare
