1. Backup - ensure you have any suitable available backups. <br />
2. Patch them in an order that keeps the systems online. <br />
3. If you are really concerned open a one off MS case in advance of the patching. <br />
4. Sorry I have no documentation for this as I do not know your specific config although I have a rough idea at overview.

<div>
i did not get the below &nbsp;???<br />
<br />
CU19 for Exchange 2013 was released on Tue 19 Dec. &nbsp;As a result, only CU18 and CU19 are supported. &nbsp;Therefore, no need to upgrade from CU13 (unsupported) to CU17 (unsupported). &nbsp;<br />
<br />
and also for below , are you sure ?? is there any article that mentioned this <br />
<br />
Also, is &nbsp;Hybrid configuration wizard need to be run after all Exchange server updated to latest CU ?
</div>


<div>
and also we are having &nbsp;.net framework 4.5 on all servers ?? so we need to upgrade .net framework to 4.6.2 &nbsp;? and what is the procedure..
</div>


<div>
You stated in your original request, that you are planning to upgrade to the latest CU --which you stated as CU17. &nbsp;CU17 is no longer supported by Microsoft.<br />
<br />
You can make an attempt to upgrade directly to CU19 however, you may be prompted to install .NET Framework 4.6.2 at a minimum. &nbsp;But keep in mind, .NET Framework 4.7.1 is now supported with CU19 and will be a requirement come June 2018. &nbsp;I would recommend installing 4.7.1 after CU19 is installed so you do not have to do it later.<br />
<br />
Not exact on the current update process, but this is what it looked like when CU16 was released...<br />

<div class="indent">
With CU16 for Exchange 2013 and newer, .NET Framework 4.6.2 is a requirement. &nbsp;If you are upgrading from a CU version prior to CU16, you must upgrade Exchange 2013 to CU15 first, then upgrade to .NET Framework 4.6.2, and finally upgrade Exchange 2013 to one of the newer, supported CUs.
</div>
</div>


<div>
as per customer need, we need to update to Cu17 not the latest one,.<br />
<br />
so can we install directly from cu13 to Cu17 ? and before cu17 install, do we need to update .net framework 4.6.2 ?
</div>


<div>
so according to you, <br />
first i can install .net framework 4.6.2 &nbsp;on all exchange server <br />
second i need to install Cu17 on all Exchange Server as per below<br />
<br />
2 Mailbox Server<br />
2 Hybrid Server<br />
2 Edge Server
</div>


<div>
Please suggest as per last query<br />
<br />
any special care for Exchange Server for upgrading to cu17
</div>


<div>
.NET Framework 4.6.2 is not supported with Exchange 2013 CU15 or older. &nbsp;So, if you install 4.6.2 before CU16 or newer, you may break Exchange.<br />
<br />
Upgrade the non-Edge servers before the Edge servers.
</div>


<div>
we are going to upgrade from cu13 to cu17<br />
<br />
so before cu17 we need to install .netframework 4.6.2 ? right
</div>


<div>
No. &nbsp;You didn't understand what I said or review the Exchange supportability matrix previously provided.<br />
<br />
To summarize, install a supported CU, then install .NET 4.6.2.<br />
<br />
Again, the CU install will tell you if a prerequisite is missing and stop the CU install before it begins.
</div>


<div>
supported CU means ??<br />
<br />
so you mean i cannot go directly from cu13 to cu17
</div>


<div>
so mean, i can install directly Cu18 from current Version cu13, and before that i need to install .net framework 4.6.2 ?
</div>


<div>
Hello,<br />
<br />
i checked currently i have 4.6.0 &nbsp;.net framework is installed on server, So now is it safe to install .net 4.6.2 before cu17 ?
</div>


<div>
Hello Todd,<br />
<br />
Cu 15 is not avialable to download on microsoft site<br />
<br />
Please suggest, how i can go for upgrade from cu13 to later version<br />
<br />
