zfs v28 solaris compatibility

[Eugene M. Zheganin]

Hi.

Is the FreeBSD v28 zfs fully compatible with solaris zfs ? I need to
switch disks between servers, these disks are SAN disks, and it's about
20T of data. I don't want to lose them. I am aware that our zfs is
compatible with Solaris, but I just want to be sure, like really really
sure. Of course I can switch back at any moment, but only if the data
won't become corrupted.

Thanks.
Eugene.
