For the past couple months I've been working on finding a way to

approaches. Then a couple days ago I started a new set of
experiments and
now I have successfully cross-upgraded three different systems using
this
technique. On the three machines that I used, all the configs that
I set up
were still in place after the upgrade. The machines behaved
normally and I
have not found any sign of problems yet. But, it would be difficult
to see
how this technique could ever be fully automated because it requires a
certain amount of manual inspection in a number of places. And it's
probably something that could not be officially supported. But at
least it
appears there may now be a technique to perform a successful 32-bit =>
64-bit upgrade. And for those who have heavily configured machines
this may
be worth a try. Anyway, here's the technique:
You sir, are a hero. I wanted to do exactly this once F11 is released
and was disappointed to learn it wasn't possible in an earlier thread
on this list (that I can't immediately find the link to).
I think I will give this a try (won't be until next month, though).
Worst case scenario is I just blat it away and reinstall from scratch,
which is what I was planning anyway.
Exactly. That's how we looked at. We had nothing to lose by trying
to do this because the alternative was a complete wipe of the system
anyhow.
And just a little tip for Rescue Mode. You can put the technique
document into your shell history like this:
history -r DOCUMENT
Where DOCUMENT is the full filepath to the technique document. That way
you can scroll to the command you want to execute without having to type
the whole thing in by hand.
