When: Sunday March 13th 2016, 10am - 2pm AEDT

Impact: Customer VM instances will be live migrated between hypervisor hosts during the maintenance window.

Any VM instances that do not have XenServer Tools installed will be stopped to enable hypervisor servicing, and then be started on another hypervisor host. To avoid this, please ensure the latest version of XenServer Tools is installed prior to maintenance commencing.

We advise customers to update VM instances to the latest XenServer Tools version once maintenance is complete to ensure optimal performance and supportability of your enviornment.

Note: this maintenance activity does not impact customers with services hosted in the CloudCentral Enterprise Cloud.
