[Sunhelp] SBU jukebox software module

[Wonkyu Chang - Sun Korea SE]

Hi,

My customer bought Solstice backup 4.2.6 software long time ago, and has used it 
very well. On today, he asked to order jukebox software module.
But, I found that only SBU 5.1 jukebox software module is available.
Can SBU 4.2.6 base software support SBU 5.1 jukebox module?

Also, does he need only to order jukebox module option when he's add new tape 
library L1000? he's try to use the bunddled SBU on solaris 7.

Thanks,
WK Chang
