Performance Report Error

Hi Im receiving this error on the performance update dashboard link:

“The performance test didn’t return any results. This probably means you’re on a local website (which we can’t scan) or something went wrong trying to access WPMU DEV. Try again and if this error continues to appear please open a ticket with our support heroes”

Another question. I use Migrate DB Pro plugin to push content/database updates from to Is WPMU compatible? Will settings we migrated if I select wpmu plugins to be loaded for the migration?
