It may be time to upgrade to vSphere 7
VMware vSphere 7 has been GA for almost exactly 1 year now. That's given all of the early adopters plenty of time to suffer through the problems and work out the kinks. We view vSphere 7 as incremental progression, rather than a landmark build. VMware has renamed a few things, and tweaked a few features, but for most of us, it is business as usual.
One notable change in vSphere 7 is that the Flash client is completely eliminated, removing attack vectors and security vulnerabilities by the truckload.
If your equipment is VMware vSphere 7 compliant, we highly recommend you upgrade at this time. Check your equipment for vSphere 7 compatibility here: https://vmware.com/go/hcl
We know that all HPE ProLiant DL and BL G9 servers are VMware vSphere ready, so go ahead and upgrade or call VMsources for a managed upgrade!
VMware vSphere 6.5 & 6.7 extended
Even if your servers won't support upgrading to VMware vSphere 7, there's good news. VMware has extended support for VMware vSphere 6.5 & 6.7 until October 2022, giving some users room to breathe.
VMware vSphere 6.0 is past end of life, however, and it is important to upgrade or discontinue production use of any VMware vSphere 6.0 based products.
