Hi Sangamesh,
in addition to RMGs answer:
There is no direct migration path from 9.7 to 10.7.
You will have to perform an interim migration to 9.12 (still using Broker 9.6).
In the documentation area there is also a document called “Supported Upgrade Paths”.
For 10.7 you should consider upgrading to Broker 10.5.
Migration from Broker to UM is not an easy task, esp. when using native pub/sub.
That is the reason why Broker has been refurbished from 9.6 to 10.5 while including the Fixes from 9.6 into the 10.5 GA version.
Regarding deprecated services:
You will have to check all the release notes for 9.8 up to 10.7 to find all services being deprecated or changed in defaults.
You can check the community forums, there is an pre-upgrade analzyer tool available for IS:
Regards,
Holger
