Upgrade FC2 to FC3 using CD, using yum, or complete reinstall?

faethon · #1 8th November 2004, 03:38 PM

With the new core 3 released today, how do you advise to go about when upgrading from FC2 to FC3?

I was thinking of doing a clean install of FC3, but maybe this is not needed if the FC2 to FC3 upgrade from CD will just result in the same state.

Will there be a difference between a clean install or an upgrade?

i much prefer clean install and play with conf again, but if you dont want to reinstall you can upgrade them, both way is a matter of personal preferences

a choice to be made

Yes, I like playing around, getting a new configuration up and running as well..

But if you upgrade from FC2 to FC3 will it completely remove any traces from FC2, and thus put your system in a state as-if you've done a complete reinstall? Or will there be minor discrepancies between the reinstall and the upgrade?

When doing an upgrade, your old config files and extra packages are left intact. However, common
componets of both systems will be upgraded to the FC3 level.

What are you considering is a common component?

According to the Release Notes, the biggest change is from /dev to /udev and, once again according to the document, an upgrade from FC2 to FC3 will handle this appropriately.

Common components are those components that the RPM system considers to be "the same program /package" - like X, KDE, Gnome (except for Ximian), all the system basics....

is it easy to do a reinstall of / while leaving /home intact?

Am I right when I say that your config files will be saved as something like httpd.conf > httpd.conf.rpmold... and the new config file in its place?

If /home is on a separate partion, then yes

If /home isn't on a separate partition, then this might be a good opportunity to make it so.

Usually the other 'way 'round - the new one gets installed as ".rpmnew" if there's been a change in the config from the default installation. In practice, I've seen it both ways...

Ahh, doesn't this mean we should update to the new configuration?

The upgrade.log file in /root will tell you which config files get saved off as "rpmnew." What I usually do (and just did) is diff the currently-used file with the .rpmnew file and see what the actual difference are and adjust the .rpmnew file with my modifications (if needed), and move the .rpmnew file over the top of the current one, or delete the .rpmnew file.

Example, I had an /etc/profile and an /etc/profile.rpmnew. The changes between the two were only my modifications, so I deleted /etc/profile.rpmnew.

I'm a firm believer of clean installs. Kinda like this ,,, when you go on a road trip ,, do ya pack dirty laundry ??

Upgrades can and many times do ,, amplify any problems you may be trying to resolve with an 'upgrade'. Store your data somewhere, somehow, any way you can. It's a lot less frustrating and you'll have peace of mind that you're not going to blow your data up. When it comes to configuring things, sound, network,etc., save those conf files with your data for fast reference and with luck, a copy paste will do ..............

I did one clean install and one upgrade. The upgrade was on a laptop. I ended up with enough half baked issues that I ended up backing up, and then wiping and re-installing. The system is seems to be much better for it. Granted, with the wonderful support in these forums and faqs, in time, most, if not all of these issues would be resolved.

Will the FC3 "clean install" create a partition or resize my existing FC2 partition to make room for itself?

My system has an 80 gig harddrive which is equally divided between XP and FC2. I would like to take part of the FC2 partition (because it has more available space) for FC3.

How do I do this?
