I have vCenter Server 6 Standard, vSphere 6 Enterprise Plus for vCloud Suites and vRealize Suite 7 Advanced license but I have not support . License Coverage End Date : 22.12.2017
I want to update vcenter 6.7u1 and ESXi 6.7u1 . is it possible so can I use these key for 6.7?
You can use those keys for 6.7, but since you're out of support just keep in mind you cannot open SRs if you get into troubles.
