Migration to ZFS file system

[battle]

The new Snapshot feature requires Opensense to be on the zfs file system.  My Opensense is on the other one.  The message that is given when your try to do a snapshot is:

"Snapshots are only available when a ZFS file system is used.
For more information on how to migrate to ZFS, please refer to our documentation or support resources."

I can't find any information on how to migrate to ZFS.  Can anyone point me to this information?
Thanks

Export and save config, reinstall from e.g. an USB medium, restore saved config.

Thanks, but bummer.  That is what I was afraid of.  I had to reinstall just yesterday because Opnsense suddenly refused to connect to my ISP modem.  The reinstall fixed it.

Then why did you not install with ZFS?

I did a recent fresh install, and got the option to use ZFS. However, it wouldn't do it and complained that I needed two disks, iirc. What am I missing?

Don't pick "mirror" but pick "stripe" when selecting the pool layout. A mirror obviously needs at least two drives.
