Many Thanks - exactly what I wanted.

<div class="content wysiwyg-content">
Last year we installed a server which has been running pretty well up until now.<br />
<br />
The server runs Exchange 2013 and Microsoft Server 2012 R2 all in one box, I guess its a pretty simple setup for most server people.<br />
<br />
A couple of weeks ago I had a bad experience trying to activate DirectAccess and VPN - Internal IPs became IPv6 and we could no longer connect to mailboxes locally or remotely, so I rolled back the changes and all began to function again.<br />
<br />
Anyway I decided that before repeating the exercise I would upgrade Exchange.<br />
<br />
Our current exchange system looks a like this - <br />
<br />
Mailbox, Client Access<br />
Version 15.0 (Build 516.32) <br />
Standard<br />
Licensed <br />
<br />
Exchange is running within Windows Server - IE. nothing virtualised and only one box, we only have 15 users so not a heavy load . <br />
<br />
My question concerns the upgrading of exchange -<br />

<h2>1. </h2>
Can I just apply the latest service pack, or do I need to up grade in stages?
<h2>2. </h2>
If the above is not possible can I just apply the latest cumulative updates?
<h2>3. </h2>
All my customisations were done either using Exchange Shell, or EAC will I loose any of these ?<br />
Many Thanks, Chris Coleman.

Upgrading Exchange 2013.

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.

Exchange
