EBS 7.3 and cluster license use questions

Hi

customer has the following active licenses on his 7.3 server.
He has questions about his cluster licenses (cluster is Sun cluster)

All "Connected UNIX clusters" but one are decommissioned but they will  soon  have the need for backups of 10 cluster nodes.

i.) Will they have to purchase more cluster clients licenses here?

They have 8 clu_unix types, so I'd have thought they'd need 3 more to  make 10.

ii.) Is it correct that cluster resources, e.g. "aabsprddb" consume a  license?

iii.) 7.3 is eol now as well, so will they even be able to get hold of  licenses if they need them?

thanks and regards
geoff
