I was lead on migrating several systems from traditional deployment to a cloud provider for a major company. Part of the migration was switching a microsoft DB to MySQL. The java ecosystem and ORMs makes this so easy it's barely worth talking about. And that wasn't the only time db migrations have some up.
Not sure if that's enough to justify ORMs, but DB migration is a real use case and there are things you can do ahead of time to greatly simplify the process.
