Our Sharepoint product group released the next monthly cumulative updates. How patching works for SharePoint 2013? Read more in the post from my colleague Stefan.

Since April 2015:

• You need to have SP1 installed!
• In case you have installed a SP1 slipstream version, please read the article from my colleague Stefan!!!
• Search enabled Farm, please check as well this article.

The format how we are providing the Cumulative Update packages has changed in 2015, means you can find all packages on our Download Center.

When you reached the download website, it is independent which language you chose, the packages are the same.

Plan to upgrade carefully, you may need more time in case the current patch level for your Farm is June 2015 or earlier! Reason is in regards to Search and psconfig. Please check the post from my colleague Stefan!

Important for all Server Applications listed above:
After any binary update you need to run psconfig or psconfigui. Please refer to the following article to find out what is the best for you: why-i-prefer-psconfigui-exe-over-psconfig-exe.aspx

You might have you own strategy to run psconfig, because it depends on the farm structure and what makes sense to reduce the downtime.

Regarding PSConfig: With August 2016 CU for SharePoint Server 2016 we updated psconfig with a couple of improvements, discussed in my colleagues blog post:

• PSConfig improved error reporting
• SharePoint Patching and Get-SPProduct -local

The news are that these improvements are now available with this December update also for SharePoint Server 2013.

As soon as possible (in case patch level of your Farm is June 2015 or earlier) after you installed the binaries, run the psconfig! Reasons are here.
