I currently have a slow old Celery 400Mhz running Redhat 8.0 as my "everything" server (email, web, ftp, etc...). I just purchased a new server (Xeon, 2x 73GB 10K RPM Ultra320 SCSI drives, DDR RAM, gigabit ethernet... etc...) and would like to put Redhat 8.0 on that as well, and move the data over ASAP, so I can get rid of the crappy old server.

How would I go about making a "mirror" of the old server onto the new server?

in /root you will find anaconda-ks.cfg and install.log which will show you how the original box was built. As for the data, it really depends on what you need to bring over. If you can isolate which directories have your data, you can tar them and copy them to the new machine. For example:

tar zcvf ftp.tgz /var/ftp
tar zcvf home.tgz /home
etc...

ftp the tgz files, or scp, or whatever to the new box and untar them in their new home:

tar zxvf ftp.tgz
etc...

I would also grab the /etc directory, since that is where 98% of your config files would be.

Sounds good! I'll try this as soon as I get the new server.

So basically I'm copying all of the data and config files, so when the files are copied over, all the servers will be configured already?

I think I'll plan on making tarballs of /var, /etc, and /home. That seems like it'll move over most of the important stuff.

Sorry if the questions are a little noobish. I've used Linux "passively" for years and years, but haven't had the time until recently to really start learning the OS.
