Hi,

I found the following post by carson very interesting and promising:

http://www.ioncannon.net/linux/68/upgrading-from-fc6-to-fedora7-with-yum/

On my main system, I installed via the dvd. A second system does not
have a cd drive.
I planned to use the above instructions; however, I did not wish to
install from net online. So, some of the instructions were modified:

On a server with a dvd drive :
1. Use the keep cache option on.
2. There will be a cache/yum/fedora directory. Copy all the rpm files
from the dvd into the /var/cache/yum/fedora/packages directory.
3. Export /var/cache/yum directory using nfs with root no-squash and writeable.
4. On the second machine, mount the above directory. Make suitable
changes in the /etc/yum.conf
5. Using rpm, update fedora-release and fedora-release-notes.
6. Run yum update

It will still need a net connection but will use it only when needed.
What was earlier in extras will be downloaded.

In my case, it took much longer than it would have taken me to
physically move the dvd drive but that would not have been fun.

One problem which gave me a fair amount of trouble was that I had
downloaded stuff from freshrpms and livna. When both repositories were
active, I hadd dependency problems. With livna alone in my case, the
problems were resolved.

One problem though - the new kernel is panicking as it can't find root
at /dev/hda5. Fortunately, the system is working fine with the earlier
kernel.
Thehttp://www.ioncannon.net/linux/68/upgrading-from-fc6-to-fedora7-with-yum/re
must be a simple solution to this problem...not found it though. The
post above emphasises lables - may be I need to do that.

A major advantage of the above scheme is that we can upgrade a machine
without stopping normal activity. Machine can continue to be used
though I can't say if all applications will work properly during the
transition.

Interesting comment on the matter of scale:
One of the comments: "depending on whether you see a 2 hour download
as a problem or not :D"

For me even with the so-called broadband, downloading even the extra
packages took longer!
Why can't bsnl mirror these sites?
