Hi,

old server.

<div>
I believe so, but how so I confirm.<br />
<br />

<div class="content wysiwyg-content">

<br />
I have created a new email server to replace the existing email server. &nbsp;This server is using Centos (a free Red Hat Enterprise clone) &nbsp;The original server was purchased preconfigured and is using sendmail. &nbsp;The new server is configured with postfix.<br />
<br />
On the new server, I have created the same user accounts as appears on the mail server. &nbsp;Ideally, I would like to be able to copy the password file from the existing mail server and install in on the new server so that all users will be able to use their existing passwords. &nbsp;<br />
<br />
Any thoughts?

Can a password file be copied from one linux machine to another?

A Linux distribution is an operating system made as a software collection based on the Linux kernel and, often, on a package management system and are available for a variety of systems. A typical Linux distribution comprises a Linux kernel, GNU tools and libraries, additional software, documentation, a window system (the most common being the X Window System), a window manager, and a desktop environment. Most Linux systems are open-source software made available both as compiled binaries and in source code form, allowing modifications to the original software. Over three hundred distributions are in active development, including commercially backed distributions (such as Fedora, openSUSE and Ubuntu) and community-driven distributions (such as Debian, Slackware, Gentoo and Arch Linux).

Linux Distributions

Linux is a UNIX-like open source operating system with hundreds of distinct distributions, including: Fedora, openSUSE, Ubuntu, Debian, Slackware, Gentoo, CentOS, and Arch Linux. Linux is generally associated with web and database servers, but has become popular in many niche industries and applications.
