Hi Gowtham,
If you can to migrate from trial cloud to local this is an export / import on file menu.
Obs: I don't know if export works on cloud, maybe some colleague can complement
If you want just to access at same time development systems from Studio is easy as Studio can connect to many servers at same time.
If you want to a system look for data from other systems you must build the bridges, like expose in one system as oData service and consume from other one.
