I need to upgrade vcenter to 7.0 in my lab, but I can find confirmation that will work with AOS, version 5.15.1.1 LTS.
Actual 6.7U3 is installed, and AOS is on ESXI 6.7U3, i can move the hosts later, when will published in the compatibility matrix (dell R640), but I have to upgrade ASAP the vcenter, thanks for the support!
