copy user accounts to other linux system


I want to upgrade my linux system from an old server to a new server (both use Red Hat 8).

Does anyone know how to do the followings automatically or in a quick manner ?

1. import all users id and password from old server to new server
2. create the /home user directory in the new server with the same rights as the old server

Thanks

1. copy /etc/passwd (and /etc/shadow if you use shadowed passwords, which you probably do) onto the new system.

2. on old server:
su
cd /home
tar -cf ~/homes.tar *
copy homes.tar from your /root directory onto the root directory of the new server
on the new server:
su
cd /home
tar -xp ~/homes.tar
I think that should do it. If there's a lot of files there, you'll want to compress the file probably. Lookup the tar man page or the like. Also, this dosn't copy /root which is root's home. You can use tar for that too:
su
cd ~
tar -cf /roothome.tar *
other comp:
su
cd ~
tar -xp /roothome.tar
If you want to grab users in smaller increments, substitue * for a* then b* and so forth with the first pair of commands.
