It's also recommended to have two usb sticks available. One custom iso with the old zfs format and one with the new one. So you can easily switch between them. | It's also recommended to have two usb sticks available. One custom iso with the old zfs format and one with the new one.

If you don't have enough free space to move a dataset completely, you can just use both usb sticks to boot either version and transfer files partially by rsync like this: | |||
# Boot usb with stability patches applied | |||
# Import the pool and load the key | |||
# Create a new encrypted dataset, e.g.<br/><code>zfs create -o encryption=aes-256-gcm -o keyformat=passphrase -o mountpoint=legacy zroot/mediaNEW</code> | |||
# Mount the format one and the new format one, e.g. <br/><code>mkdir -p /mtn/media{OLD,NEW}</code><br/><code>mount -o ro -t zfs zroot/media /mnt/mediaOLD</code><br/><code>mount -t zfs zroot/mediaNEW /mnt/mediaNEW</code> | |||
# Once mounted, you can use rsync to transfer (part) of the data:<br/><code>rsync -avp /mnt/mediaOLD/Music /mnt/mediaNew/</code><br/>Notice: In the source folder there's no trailing "/" so that in the destination location provided that whole folder will be created. Of course you can also just start with a sub folder if one is too big. | |||
# Rsync (or copy) over as much data as you can. Since the old format dataset can only be mounted as read-only, you'll have to boot into the other usb stick with the old format, mount the old media folder and delete files in there. You may also need to delete snapshots first. | |||
# Afterwards boot again into the new format usb stick and repeat. | |||
Of course if there's no sensitive data that needs encryption, you can just boot up into the old format, create a new, non-encrypted dataset and start moving files over. | |||
