  And it works miraculously well. I have seen a very large Oracle DB with many reads and many updates migrate with no effects outside of a big spike in sql execution times for the few hundred milliseconds it takes between the source pause and the destination resume. Seen various GCP bugs, mostly VPN and pub sun, but never anything from migration. They migrate about all the instances every two weeks, so it is an often exercised path.
