In case Cluster had not been upgraded to version 6.5.435.1 for Ubuntu or version 6.5.639.9590 for Windows, you are required to first upgrade the cluster to the latest version of 6.4. This is version 6.4.664.9590+ for Windows and 6.4.661.1+ for Ubuntu. After that you can safely upgrade to this 6.5 refresh release version.
