@rubesh_u Please see my inline answers to your questions.
1.what will happen if two update sets are in progress at the same time?
Answer: Multiple update sets can remain in in-progress state at the same time in same or different applications scopes. The updates only get captured in the current update set.
2.how many update sets should be in progress per scope?
Answer: There is no such defined limit, however in order to avoid confusion you should keep only those update set in progress which are related to the functionality you are building, rest can be set to ignore or complete.
3.should i create update set for each scope when the story requires to switch scopes?
Answer: Yes, there should be separate update set for each application scope. You can also choose to batch the update set by creating a parent update set and child update sets.
