preupgrade or netinstall from i686 to x86_64

2011-09-01 Thread mcforum 
I don't see an option in preupgrade to go from F13 i686 to F14 x86_64.
Is it possible?

You could try but you really would not like doing it.  If you have 32 bit 
programs you want to continue to use, There is a "multilb" install that keeps 
the ability to run such.  It requires synchronizatrion of all the system code 
and libraries between the x86 and x86_64.  They are constantly getting out of 
synchronization causing yum to fail until the offending package can be manually 
brought back into sync.  Ffinding your way from an upgrade of F13 to F14 then 
to 
F14 with updates will be painful.  You can keep some of your customization with 
a backup of /home and anything else you want to keep.  The system settings 
stored in /etc are much more difficult.

If you have the disk space you could install the F14 x86_64 as a dual boot then 
get the various parts of your earlier system and copy them to the new.

Yes, it is possible, but (for me at least) it entauked a whole bunch of
grief.

What I did was to use the F14 x86_64 install DVD, and do an upgrade.

This is not an officially supported upgrade path (and I think it even
tells you that and gives you the option to either abort or continue).
I chose to continue, and it upgraded a whole bunch of RPMs, but, in the
process, I ended up with a lot of duplicate RPMs of mixed architecture
(F13.i686 & F14.x86_64) for some set of RPMs.  I ended up going through
my RPM list by hand and fixing up what I could using various techniques
(yum update, rpm -i --force, rpm --erase --justdb, a couple of scripts
which removed both versions and then re-installed the x86_64 version,
whatever I could get to achieve what I wanted.  It was very time
consuming, and the yum error messages would take a long time to print
out, and in a virtual console, I often could not see the entire output
(the graphical UI was not initially working, and was one of the last
things I was able to get working).

Fedora should provide a better upgrade path for changing architectures
(at least for i686->x86_64, I'm not sure it makes much sense between
incompatible architectures), but, their official suggestion is to just
"re-install" from scratch to avoid the grief that I went through.

preupgrade or netinstall from i686 to x86_64

I don't see an option in preupgrade to go from F13 i686 to F14 x86_64.
Is it possible?

Or is it possible with an F14 x86_64 netinstall iso disk?
