upgrade path to NBU 7.6.1.1 from 6.5 on Solaris 10 (sparc)

Hi,

my understanding that the upgrade path for NBU 6.0  to 7.6.1.1 goes from 6.0 to 7.6 first and then from 7.6 to 7.6.1.1, based on sort search.

Customer ask to upgrade NBU from 6.5 to 7.6.1.1 directly on Solaris 10 (sparc), is this possible? 

Thanks
