hi everybody,

who knows how can I move all users from one machine to another ?

I`m using Centos 5.2. Is there any software for fast migration of huge amount of users(with passwords and bash environments) ?

You need to backup this files: /etc/passwd, /etc/group, /etc/shadow, then backup the directories of your users like /home/user1, /home/user2 and just copy the directories on the new machine and from passwd and shadow and maybe group lines related to those users like this:

cat /etc/passwd|egrep 'user1|user2'
cat /etc/shadow|egrep 'user1|user2'
and also maybe from /etc/group if the users have some special group.

Good luck!

I forgot to write that migration will be from SUSE 9 to Centos 5.2.

Is there any diffrence in this case ?

Well normally no, when it comes to passwd, shadow and group, but some "profiles" and "settings" of the users may not work, but its not something to go crazy over, the move i've done it from CentOS to Ubuntu Server and it worked... so it should work for u too.
