Many z/VSE users run their systems in z/VM guests. Therefore I want to remind you, that z/VM 6.2 end of service is June 30, 2017. Please migrate to z/VM 6.4 to stay in a supported environment. You can find the end of service dates for z/VM releases here . There you will also see, that z/VM 5.4 and z/VM 6.3 end of service is planned for December 31, 2017. So it's time to plan for a z/VM 6.4 migration too.
