What does End of General Support (EOGS) mean? 
General Support is what you use to get support from VMware. When General Support ends, the product moves into Technical Guidance support.

Technical Guidance is primarily available via the self-help portal, telephone support is no longer available. Support requests can still be raised however support is limited. Critically, no bug fixes, security patches or updates are released while in the Technical Guidance phase. 

Important changes
With vSphere 6.x becoming EOGS that also means the end of Windows vCenter Server instances and for the Flash based vSphere Web Client. With vSphere 7 VMware have moved to a Photon-OS based vCenter Server and a HTML5 based vSphere Client.

We are not prepared what can we do?
