title: oak version upgrade in aem
body: <p>I am using AEM 6.1, and upgrading my AEM instance with SP2. I have installed CFP 3 and SP2 in AEM 6.1. earlier my oak version is showing 1.2.7 but after installation of SP2 and CFP ; oak version got downgraded to 1.2.18. but blog<a href="https://helpx.adobe.com/experience-manager/release-notes--aem-6-1-cumulative-fix-pack-.html" rel="nofollow noreferrer">1</a> say: <em>If your instance is running a higher version of Oak compared to the Oak version of the CFP package, the latter will not impact your current Oak version.</em></p>
  
  <p>Could you please let us know is there any way to upgrade oak version in my AEM instance? if not does this oak going to impact any functionality in our existing instance?</p>
