NetBackup AIR for old Backup images

I have implemented AIR in my existing NBU environments and it is working correctly as designed for any new backup is performed. Is there a way to get one of the old backup image (The backup which was performed to Tape prior to implementing AIR) duplicated using AIR SLP so that it can be imported in my Target Master at DR site?

My environment:

Source Master: NBU 7.5.0.6 running on RedHat Linux 5.5

Target Master: NBU 7.5.0.6 running on RedHat Linux 5.5

DataDomain (Both Sites) DDOS 5.4.0.8

OST Plugin 2.6.1.0
