Upgrading CloudStack

This document contains the instructions for upgrading CloudStack from prior releases, to the current release. Please read through all sections carefully before starting.

From ACS 4.16 onwards, seeding of system-VM Template is optional, as this will be taken care of by either the upgrade process or in case of a fresh deployment, registration of the systemVM Template(s) is handled during the addition of the first image store to a zone. The cloudstack-management package will now include the systemVM Templates for KVM, XenServer and VMWare. In case Templates aren’t already registered either prior upgrade or during fresh installation, ACS will handle the Template registration automatically, by mounting the secondary store onto the management server, copying the respective Templates to the store and then creating the file.
