RSView32 is most similar to FactoryTalk View SE, so the migration tool works only in FactoryTalk View Studio for migration to SE Distributed or SE Standalone.
Consider a function like a Button; in RSView32 and FactoryTalk View SE, a Button object has an Action which can be any RSView command like Go To Display or Set Tag or Execute Macro.
In PanelBuilder and FactoryTalk View ME there is no Button object, but rather Momentary, Maintained, Latched, and Multi-State Pushbuttons, and Ramp buttons, and Macro buttons, and Go To Display buttons. Everything's defined into simplified objects.
So in short: No, you cannot import an RSView32 project into FactoryTalk View Studio ME.
