Very Computer

I just tackled the same project.

Basically I tar'd the user directorys and the mail spool dir, FTP'd them
over, and unpacked them on the new system.

Im not sure if the passwd and shadow password file would be compatible in
your case or not but I copied those over also and they worked for me.

If you run virtual domains then you may also have to concern yourself with
sendmail.cw and httpd.conf. Also /etc/aliases if you used it.

lastly just to be sure I ran a find for all files that were not in the
users home dirs that had changed since the original OS was installed. I
ran that to a list so I could browse it. That showed me a couple files I
had missed and some additional packages that we had installed which I had
forgotten.

Sure I'm a guru but beware of asking guru's what operating system you
should get. Guru's tend toward the most irritating system they can find.
Thats how they get to be guru's. Instead ask someone who uses a computer
everyday and still knows nothing about computers.   Me?  Oh, I use Unix.

I oid this my doing a minimal install on a new drive.  I verified it
would boot right (it did).  Then I mounted the old drive as /dev/hdb and
copied over stuff into it's rightful place.  Be sure to read the Hard
Drive Upgrade-HOWTO on which directories to copy (all but /proc) and
other helpful info.  Lilo gets me usually....

Just be sure you clean up your /etc/rc.d directory and back up the newer
/etc/lilo.conf if the partitions are different.

By doing the minimal install I ease my * pressure a bit and don't
risk fsck'ing the LILO part.  Copy the stuff over is a piece of cake and
the entire process should be very painless.

Hi,
    I need to migrate a old slackware linux to a new PC installed with
RH. How can I transfer all user account, include password, mail spool,
home directories...etc to new PC?

Thanks

        - Setup NFS on both computers
        - Mount the old box in a directory in the new box
        - Copy the files /etc/passwd, /etc/passwd-, /etc/shadow, /etc/shadow-,
/etc/group, /etc/group- from the old box to the new box.
        - Then you have to move the /home directories:

        let's say the old box is mounted in /old in the new box, do this:

        cd /old/home

        tar cf - . | (cd /home; tar xvf -)

        This will copy all the files in the old box /home to the new box home
preserving ownership. You can use the same procedure to copy the files
in /var/spool/mail

        I've done this successfully in at least 4 boxes.

        []s,
