+## Switching to a New Docker Provider with DDEV
+
+If you've tried out a new Docker provider and have decided to switch, use [this tip from the FAQ](https://ddev.readthedocs.io/en/latest/users/usage/faq/#how-can-i-migrate-from-one-docker-provider-to-another).
+
+The bottom line is:
+
+* On the old Docker Provider, `ddev snapshot --all` will create database snapshots of all your registered projects (the ones that show up in `ddev list`). 
+* Then stop the old Docker Provider and start the new one.
+* `ddev snapshot restore --latest` in each of your projects will restore the database snapshots.
+
+Note that OrbStack has built-in migration from Docker Desktop; it prompts you at install time. I haven't tried that out.
