Short question:
Is there a way that I can take the RPM database from an existing FC2
machine, plop it onto a new FC4 machine, and run some version of a 'yum
update' to make sure all the packages I had installed on the old machine are
installed on the new?
Background:
I lost a partition on my home server a short while ago. As a result, I've
decided to replace the old drive with a pair of RAID-1 drives. The old
machine is running FC2; I want to be at FC4. My plan was to take out the
old drive completely, install PC4 on the pair of new drives, and migrate the
old data over from the old drive. Ideally, I'd like to make sure the
software I've installed on the old machine gets installed to the new one
also. Is the old RPM database the key to this procedure?
Thanks for your help,

From my experience and from things I have picked up on this list is
there are enough differences that it won't work that easily.
What has been suggested in the past is to make a list of installed
packages using "
yum list installed |sort > installed.txt"
Then doing a clean install and comparing the two lists. You could
strip the package mod numbers and then just diff the files. Heck, you
may even be able to feed the text file into yum and process it from there.
Copy the config files but there are enough differences that it may be
easier to just redo the configurations.
I am no expert but this is a start.
If I understand correctly, if you just move or convert that rpm
database, you will have a database that says packages are installed
when they aren't.
I would personally take the time to install the packages manually as
your needs may have changed.
