It is, for the traditional or DVD method. Not for zypper dup.

Yep. it is supported. But as I don’t have to make that jump, I can’t write
bugs on it 
But probably I have reported bugs like that (yep: at least 647333, 693230,
693338)
I know it is supported, but I have no idea where this is documented, if it
is. I have been told that by people from Novell in the mail list over the
years, so finding an email where it says that is pretty difficult.
I remember one conversation when I thought that the zypper dup supported a
jump of two versions, and they said “no”. Probably in that conversation it
was acknowledged that with the DVD method it was. Ah, no, it was not me who
asked, but a Novell employee:

It will not be supported - even if it may work.
