Need to import catalog information from Backup Exec 2010R3 to Netbackup 7.5

Hi,

We  are having Backup exec 2010 R3 server with DD configured as VTL. 

We have installed new server with Netbackup 7.5 with the same DD as the backend.

All the servers have been migrated from Backup exec to Netbackup and the backup is running fine in Netbackup.

My query here is, I need to migrate the catalog information resides on Backupexec server to Netbackup which is for old backup. So that i can decommision the old backup server and perform the restore request  from Netbackup for the old backups which are taken in backup exec.

Can you please let me know how i can i do this.

Regards,

Surya
