This largely depends on business requirements—of course, given
unlimited time, anything is possible. There is enough implemented
in Samba 4.x that it is possible to achieve Microsoft-less servers
(as long as you don't have requirements which depend on <b>other</b>
Microsoft components, such as IIS or any of the Microsoft
platform-specific proprietary applications which will run on neither
Wine nor Mono).<br>
<br>
Bird's eye view:<br>
<ul>
<li>Migrating from an existing AD infrastructure to Samba 4 is
relatively easy, since it can replicate back and forth. I need
to do testing with newer versions of Windows, but I'm lacking in
licenses on those. I can say that it's really easy to migrate
from Win2k and Win2k3 to Samba 4. It should be relatively easy
to migrate from 2k8 to Samba 4. I cannot say anything about
2k12 because they changed several things, but it should be at
least possible.</li>
<li>You'll need to test, test, test, test!</li>
<li>If you have <u>applications</u> which run on the Windows
Server (e.g., if the Windows Server is providing more than
infrastructure services), this can be a problem. Some
applications can be migrated to run on a Linux server using Wine
or Mono. (Older native-code applications can typically be run
under Wine; ASP.NET or applications which rely on the CLR will
require Mono.) Each application must be <b>thoroughly</b>
tested by its actual end-users to ensure that all functionality
used in production is tested.<br>
</li>
</ul>
<p>Permissions can sometimes be an issue, but once you have the
initial setup there complete (you'll need to internalize an
understanding of Windows ACL --> POSIX ACL mapping), you'll be
fine.<br>
</p>
<p>There is a module for Samba now, too, that will use btrfs for
implementing things like volume shadow copy service and so forth.
I have not played with this yet, however I plan to do so
(hopefully) soon.<br>
