Unfortunately in this case you are stuck doing a reload. Anytime I'm about to do a migrate import of a large/complex configuration and/or I have any suspicions whatsoever that it might fail, I perform a migrate export of the "clean" config first before running the migrate import. Restoring the "clean" copy after an import failure will still take awhile, but it sure beats the effort of a reload...
I would like to understand more about the failure you had on 3 domains and see how it can be addressed. Please, feel free to contact me - email@example.com.
