First you must ask your certification body whether they will audit your organization according to ISO 9001:2008 or ISO 9001:2015.
If the certification body will conduct re-certification according to ISO 9001:2008, then you don't need to do much more compared with previous surveillance audits. You need to make sure that internal audit is conducted, as well as management review. Check the status of corrective and preventive actions, see if there were any recommendations or non-conformities identified during previous surveillance audit and make sure that they are removed.
If the re-certification will be conducted according to ISO 9001:2015, you will have to make a transition to a new version and there will be some significant changes.
My suggestion is, if they plan to re-certify your organization according to ISO 9001:2015 to reschedule your certi fication to August 2015, in this way they will have to re-certify you against ISO 9001:2008 and you will have enough time to make transition in following years. But if you decide to do re-certification against ISO 9001:2015, you will have our full support. We are planing to launch the free webinar that will explain how to make a transition to a new version of standard and our new documentation toolkit will be launched as soon as final draft of the standard is released. So, either way, you can accomplish your re-certification.
