How to upgrade Debian 8 stable to the unofficial port (iMac G5)

[tuxayo]

Hi :)

I installed the last offcial Debian 8 iso. Picking "install" and not
"install32" IIUC I have a ppc64 install.
Or maybe not, I don't see a ppc64 package here:
http://archive.debian.org/debian/pool/main/f/firefox-esr/

ppc64 seems the most relevant choice for a G5 to gain some performance
and to have any chance of having a full browser running on that
hardware. From the emails in the past months, I see it will likely crash
but there is hope that it might work at some point.
Still better than Firefox 52 on the powerpc port. (segfaults every 2 min
on Debian 8)

How to upgrade from Debian 8?
Should I just change my source list to adapt the right part to point there?:
http://ftp.ports.debian.org/debian-ports/pool-ppc64
there is also
http://ftp.debian.org/debian-ports/pool-ppc64/main/f/firefox/
any preference?

And then just
apt update && apt full-upgrade && apt autoremove

I'll also try to install debian-12.0.0-ppc64-NETINST-1.iso
But the past I tried debian-12.0.0-powerpc-NETINST-1.iso (because I
though ppc64 was ppc64el)
And it failed to boot:
Invalid memory access at
#SRR0: 00000000.020837dc #SRR1: 10000000.00083030

Oh ok, thanks for avoiding me trouble due to not knowing this :)

Yeah, not doing that, there are already enough odds stacked again me for
trying to use such old hardware for browsing the modern web ^^"
