Can someone point me to some good reading on = ths=20 > subject -=20 Didn't you ask exactly this question a few days ago? I replied then, but the reply went to the list, and maybe you aren't subscribed? Anyhow, this is what I said then: http://lists.freebsd.org/pipermail/freebsd-questions/2013-December/255127= =2Ehtml To which I shall only add this: if you can't find anything much written about doing the ort of upgrade you are contemplating, it's probably because the process is pretty unremarkable. You just do it and it generally works fine. ZFS is not what is likely to cause you any grief. For general advice on upgrading, see the handbook: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/updating-upgrad= ing.html If you have any more specific questions after reading that, please feel free to ask again here.
