Overwriting Red Hat 7.3 files?

[Dakota]

Hi,
I am currently running Red Hat Linux 7.3 and would like to upgrade to version 9. It is dual-booted with Windows 98 (via a Linux boot disk inserted during boot up). I have already downloaded the 3 newest ISO files from Red Hat. What is the best way to upgrade to version 9?
1) Erase all of the data in the Linux partitions and do a clean install?
2) Write over the existing files on the partition?
3) Another way to upgrade directly to version 9 from within version 7.3 (???)

Thanks in advance for your help,
Dak

I can't help with your decision. However, I have installed linux a number of times and do have some thoughts on the task.

First, I don't think you can "write over existing files". The installation function for most distros requires you to format the partition where you install which means the same as erasing the existing files. That is, you need do nothing like removing or deleting files; the install formats and they are gone.

Second, you will thus need to back up any work, such as wordprocessor files or whatever other work, or it will be lost.

Third, if you have enough space, create a separate partition and call it some name, such as /home which will not be screwed by a future install. Put all your work in there, and when you install another version, don't format that partition and all your work will be there for you. I have done this a number of times, and it is a great thing to have your work in an isolated space.

/usr will be hosed, which is why I use /home for that safe place.

I know nothing much about upgrading, except for sad stories from those who tried it, mostly stating they would do a clean install next time.

I hope you get some really good help from those who know more.

Dakota,

Having upgraded from 7.0 to 7.1 to 7.3 to 8.0 and finally 9.0, your upgrade should go fine.

When you start the install process, you have a selection that allows you to upgrade an existing installation. If you select that option, you can then customize your install (if you desire) or just let the process update what you already have installed.

OTOH, irlandes is right. If you don't already have a separate /home partition, now would be the time to wipe your current Linux partition, split it and make sure you have a separate /home partition. That way you won't lose files next time you decide to do an upgrade or change distros.

HTH.

Thank you both for the information. This really helped a lot.
