Don't worry about migration for the moment. It seems that the problem is your project has compilation errors somewhere. You need to be able to build the project(s) before you can make any progress with things like migration.
Go to the 'Build' menu and choose 'Build Solution'. Do you get errors? What are they? There may be more than one error, only focus on the first one. What is the exact error message? Does it refer to a line of your code? Which line? Show us the line
of code with the error (and the method it is in if the method is not too long).
(If 'Build Solution' doesn't give errors then do a 'Build'=>'Clean Solution' and when it finishes try the 'Build Solution' again)
