Migrating ZFS on Linux pools to FreeBSD

Hi everyone,

I'm migrating a home HP Gen8 Microserver from Debian Jessie to FreeBSD 
10.2. I have two mirrored ZFS pools created with the ZFS on Linux port, 
and want to access them on FreeBSD.

I understand FreeBSD's ZFS implementation is more mature and pre-dates 
the Linux port, and some web searches indicate the two may not be 
entirely compatible. Most recommendations seem to be not to run Linux 
and FreeBSD off the same pools, for example:


Does the same hold true for just data stores, and ones that are being 
migrated over without being accessed by Linux again? Are there any 
practical limitations to just using a ZFS pool created on Linux?

If there’s reasonable doubt of issues I'll just rebuilt the pools under 
FreeBSD, but would be great if I didn't need to do that. It'd be cool if 
it’s just a # zpool upgrade away hah :)
