LUN merging in NS 480

Hi All,

I have a NS-480 , and has 120*8Gb Luns are assigned to old HP servers I need to migrate to Unity ! I cant afford 120 LUN iD's for only960 gig !

here is the question

1 ) is there any way I could merge all this LUNS to a single LUN .

2 ) Can I create a destination LUN of 960 GB and do the migration for all the LUNS at a single destination ...will this work ? 

please note that these are old servers and We are about to De-commission those , how ever , we are trying to save this Read Only 960gig

Thanks
