After updating vcenter server 5.5 for windows to vcsa 6.5 and after updating vsphere replication 5.8 to vsphere replication 6.5 it only appears in flash client and not in html5. how do I make it appear in the html5 client. In December many browsers will not work flash.
it depends on which version you did upgrade your vCenter Server to. vSphere Client (HTML5) was under development when 6.5 version was released.
In one of the updates to vSphere 6.7, vSphere Client was considered as complete. Now it is still developed and VMware adds new features to it.
So I suggest you should consider to upgrade your environment to the latest vSphere version.
