The support status of Xen changes to End of Support in OnApp 6.5. Please note that we will no longer develop features for Xen, or provide full support for Xen compute resources in OnApp clouds. You may migrate your VSs from Xen to KVM.
CentOS 6 reached End of Life and is no longer supported. That is why we recommend you upgrade to CentOS 7.
This guide provides instructions on how to upgrade OnApp Cloud to the 6.5 version. You can update to OnApp 6.5 from OnApp 6.4 and OnApp 6.5 Edges. Depending on the version that you have, refer to one of the following documentation sets.
