Replacing all disks - best practise?

[Sideways]

Hello

I have a N54L with one single drive and a 3 drive zfs raid. I now want to replace all those with a 4 drive zfs raid - all new 2TB disks. Is there a best practise to migrate all data to new drives? I have FreeNas 9.2.0 running plex, couchpotato and a few other plugins. The jails reside on the 3 drive zfs raid.

How did you end up doing this?

I gave up and rebuilt the system from scratch on the new array. I couldn't figure out how to move the jails to external storage and then back to the new disks without messing things up. So finally I decided it would be faster and safer to just start over.
