Upgrading from 7.3


I have been running RedHat 7.3 for a very long time and it has been just wonderful.  I am quite happy to stay with this build as all the things I need from linux are working well (internet access via ppp/adsl, firewall, file server to my kids, ip forwarding and masquerading (internet access for the kids), good java programming environment with eclipse and a CVS server over ssh).  

However, I am finding that a lot of new things that I would like to try and explore will not install (via rpms) because of the age of libc libc++ etc...  For instance, I had to build the jikes compiler from source yesterday because the rpm would not install :-(

So, here is the question.  How painfull would it be to ugrade to the latest version of RedHat (I don't even know that the current version is)?  It took me a long time to get printers, firewall and adsl to run properly.  Would I lose all that and have to redo them?

Also, if I have built jikes on this machine and upgrade to a later linux version, will the jikes binary still work or do I need to recompile it?

Can someone suggest a reasonable migration path?

Many thanks,

    The latest RedHat Linux is Fedora Core 2. You can get it from the following website
http://www.fedora.com   (3CDs, the forth ISO is SRPM)

    For migration from the previous version to the newer version of Linux, it depends on how well you know the Linux.
Most of time it is painful especially for the first time migration.

    Usually, you just backup all the configuration files (email, ip forwarding and masquerading, CVS, ADSL, firewall rules...)
as well as your personal setting (.bashrc, .profile, .Xdefaults, .gnome ....) Then install the latest Linux and restore those
configuration and setting. Before you restore to the new system, please make sure backup the original configuration files
which come with the new system because some new version of softwares may not take the old configuration.

    So list the applications you currently use and back them up. Check the website when you encounter the issue after migration.

    My suggestion is either setup the new box or install on a new disk. So you can roll back or do comparsion easily.

Good luck,
