Upgrading Exchange 2013.

Last year we installed a server which has been running pretty well up until now.

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.

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.

Anyway I decided that before repeating the exercise I would upgrade Exchange.

Our current exchange system looks a like this -

Mailbox, Client Access
Version 15.0 (Build 516.32)

Exchange is running within Windows Server - IE. nothing virtualised and only one box, we only have 15 users so not a heavy load .

My question concerns the upgrading of exchange -


Can I just apply the latest service pack, or do I need to up grade in stages?


If the above is not possible can I just apply the latest cumulative updates?


All my customisations were done either using Exchange Shell, or EAC will I loose any of these ?
Many Thanks, Chris Coleman.

1 & 2.  You can install CU10 (the latest).  It will apply SP1 and all updates to your RTM version.  Your version of Exchange is almost 3 years old and if you had to call into support they would have you upgrade before getting very far into the call.

3.  You shouldn't lose anything.  The only thing you might lose would be if any customizations took advantage of "holes" that were plugged in the updates.
