SharePoint 2010, Service Pack 2 and the Cumulative Updates

Each time when a service pack comes out for SharePoint, there’s always a bit of confusion around how the Service Pack affects cumulative updates. Let me explain the state of SP2 with the June and August CUs. Although the June CU and SP2 came out at the same time, the June CU has a lower build number(14.0.7102.5000) than SP2(14.0.7015.1000). In order to build SP2, which is a longer process than building a CU, the SharePoint code base branches. SP2 and the June CU are in development at the same time. What this means is that in order for the later release(SP2) to include the changes from the earlier release(June CU), the code branches must be merged. Unfortunately this rarely happens when SharePoint Service Packs are released, due to tight deadlines. What this means is that Service Pack 2 does not include the changes that are in the June CU. If you install the June CU and SP2, you will get none of the changes that are included in the June CU. Since SP2 has a higher build number, it’s version of SharePoint files overwrite the June CU’s versions. Since Cumulative Updates are indeed cumulative, you’ll need to install the August CU(14.0.7106.5000) to get the chances that were included in the June CU. I hope this helps folks understand a confusion situation.

    Hi Ron, taken from my Central Administration : Manage Patch Status page, I have (among all the others which are also 14.0.4763.1000)  Microsoft SharePoint Foundation 2010 Core 14.0.4763.1000 Installed – I have just updated TFS to Update 3 and didn't notice any change to the SharePoint install. I would like to keep everything up to date including the SharePoint. I would at some point like to update both to 2013 at the same time as well and want to ensure that both stay up to date with patches. I have downloaded wsssp2010-kb2687464-fullfile-x64-en-us.exe and had planned on running this after hours one night with my setup service account that installed everything initially. Do you foresee any problems with this strategy?
