Is it that easy now? I actually was in this situation about 3 years ago and found I could not simply mount the ZFS drive - and I cannot recall exactly why. I think it had something to do with the pool…configuration(?), and I went down a rabbit hole trying to sort it out. Fortunately in this case the tradeoff in time was more valuable than the data (it was a system drive on a small SSD) so I had the option to ditch my efforts with little to lose. But, I did spend a handful of hours on it with no traction.
I was able to transfer a zfs pool from a linux server to a freebsd server with different hardware simply by moving the physical disks to the new server.
For me ZFS has been rock solid, even with power cuts during running vms(linux and windows) and a scrub.
I even managed to steal away enough ram from a server so that ZFS produced a stacktrace in dmesg, no data corruption, even on running vms.
