User Migration: how do you move /etc/shadow?


Hi, I am moving users to a new box which will completely replace the old box.

I've done a good amount of searching and noticed that everyone that's done this first starts off by moving /home and then the passwd, group, and shadow files over.

Everyone seems to do this in a different way with different precautions... namely some suggest to just copy the passwd, group, and shadow files over replacing the ones on the new machine. However since daemons and other system related UID and GIDs might be different, it's best to just copy over the users themselves.

I did this with group and passwd, but then I realized that shadow is an encrypted file, so I was unsure how this method would work with shadow. Can I simply edit out the parts I dont need from the shadow file from the old server and cat shadow.old >> /etc/shadow?

Thanks, I appreciate any advice.

How many users and groups do you need to do this for? If it's not that many, why not just go ahead and set up the users and groups on the new box. This can cause a few unforeseen problems by moving /etc/shadow although I'm sure some people do it.

several dozen users and about a dozen different groups.

Is there any way to turn shadowing off on the old server temporarily and then copy things over?

thanks for your response

I've moved my users as you did to my new box also.
but it works fine.
you might be needed to synpasswd after finished move.

Greets..

Would you guys have a more detailed description about migrating users,,
Im planning to move 70+ users from Fedora FC1 to Xandros 2.0.. In the past i have simply bash'd a little script/batch file using adduser/useradd... Is there a better way to do this.. as my way involved manually reseting every pass..

It would be just as good if there was some way to turn off the passwd conformation.. or maybe an expect script that would handle the passwd nag..

If im way off base please let me know.. 16yrs of windows has clouded my brain..
