Let's develop a howto to upgrade from fc2t3 to fc2

[ilja]

hi,
in 5 days FC2 will be released. And many of the users who use FC2t3 now will want to change to FC2. I think there will be a lot of questions about this topic, so I propose to write a howto before the problem exists.

Unfortunately I am one of the fc2t3 users. It happend by accident (I will never play with apt-get dist-upgrade again ;) ). So on 17th may I'm going to upgrade it. I think the best way will be not just to update my old installation, but to delete it and install the stable release. So I need my home folder to be safed. So I move my /home/ directory on a new partition. (http://www-106.ibm.com/developerworks/library/l-partplan.html) .
What do I need more ? /var/ ? /etc/ ?
I don't have anything interesting in /var/www or else I would backup it too.

Then I change to init 1
umount /home
cd /
and then rm -rf

Is there a better way?

Ok, because I want to make a networkinstallation I will need the boot and modul floppy before. Where will I be able to get them?

Now I boot on this floppy (or cd for others). Then I choose to install to the root partition I had before. And will choose my old /home partition as my new /home , and ask Fedora not to format it. Then the other things should be normal.

Then I add the users I had before and that's it.

What was forgotten by me? What is wrong? We have 5 days time, so it can be perfect at the end ;)

Yes, This is not necessary, during the install process (Anaconda disk druid) you can select it to format the partition that you are installing to. Ie you don't need to do this manually.

We have 5 days time, so it can be perfect at the end ;) I don't know about the floppies (I use CD) but the boot.iso is 5 megs and does everything I need it to. Also I find it easiest to simply download the isos onto my /home partition and then do an install from HD. It doesn't allow you to select the /home drive from install (you can't mess with the partition that you are installing from) but that is fixed by a simple line in /etc/fstab when you are done.

Also make sure that the user that you create in FC2 final is the SAME name as your old user (case sensitive as well) as otherwise it will create another home folder that is different than the one that you had. Thats all that I can think of now though.

Where do I get it from ? Is it a part of standard mirrors? //edit: I got it : http://download.fedora.redhat.com/pub/fedora/linux/core/1/i386/os/isolinux/

Then I mix something up with another distribution. I thought it allows you to choose mountpoints during the installation. Good to know.

That's not bad. Thank you.

Your up early Bana.

[Bana]

Yes, I am actually late for school :D (my mom is not feeling well so I am missing 1st period so she can drive me later).

Should we apply for some webspace from tux? We could then lay out all of this information a little better. (although I have no web development skills).

[ilja]

We can make it as an article here.

[Bana]

I went ahead and moved this to the HOWTO forum (since it IS in fact a howto). hehe

Getting back on topic please.

[ilja]

To get back on topic ;)

Do you need the old /etc/ stuff ? And what out of /var/ do you still need? /var/www is nice to backup what else?

[Bana]

generally the most used things (and edited) frome /etc/ are yum.conf X11/xorg.conf and fstab but other than that I can't think of any.

yum.conf will look in fc2 total different from fc2t3 (not testing) and fc1 (not 1 ;) ) So maybe it is even easier to build it from the scratch. fstab I would agree. X11/xorg.conf is for fc2t3 also ok.

[Bana]

okay so just fstab and xorg? that's what I was thinking as well (yum.conf wouldn't be altogether useful) also the xorg.conf would just be a backup in case something didn't work (let it autogenerate a new one and then use the old if something is wrong).

[ilja]

Thank to Ug, we have an understandable version of the howto .

how is it?

* I want to insert: Please unmount all the mounted devices, except of the one mounted as / not to delete them. You can make it with umount {path] e.g. umount /mnt/floppy or umount /mnt/win . Or else all the files on all mounted devices will be deleted !

for the sake of simplicity:
u dont need 2 "#rm -rf."
the anaconda installer will find your fc2t3 or fc1 partition and ask for update instead choss new installation.
than go on as described above

Q: What about the files "/boot/grub/menu.lst" and /etc/sysconfig/rhn/sources" ?

/boot/grub/menu.lst:
The boot menu showing the choice of loading different kernel-versions / harddrives / non-linux-os
-> If you've upgraded to kernel 2.6.5-1.358 in FC2T3, remove all other kernel entries according this partition. Leave additional entries (e.g. FC1 on hd(1/0) untouched)

/etc/sysconfig/rhn/sources:
up2date repository file.
-> Same procedure as yum.conf: Needs to be modified for FC2 final.

[harlekin]

i would let the anaconda installer make the new grub.conf entries. it should find the toher bootable partitions by itself.
for up2date and yum i would rather add the needed third-party repositories to the new file from final 2 than using the modified version of 1.92.

hi harlekin,

will it be a clean installation? It shouldn't have any buggy, testing apps left and be stable. Or will it only upgrade the test version? the rm -rf is only to make sure, that nothing testing will be left.

P.S. We are allmost neighbourghs, I live in Aachen ;)

[tuxinaredhat9]

yeah, I just wanted to know if you might want to make this post a little clearer, I can post it on my site(fedoradocs.net (http://www.fedoradocs.net)). I was thinking it might work to offset a lot of the questions if that would help you guys out at all? Thanks for your time and consideration.
