Not much to it, assuming that you have network connectivity between the two CM systems. Just create a SIP trunk between the two CM systems and make sure the inbound CSS on both ends has visibility of the partitions that it needs to be able to route the calls to your needs.

is it compulsory to create new partitions ,New CSS to the 2nd  call manager (10.5) inside main call manager (11.5) ?

No. Whatever you have that works for you can be used. It's just simple call routing, nothing special.
