My 2008 r2 virtual server running on esx6 has sql 2008r2 installed on it and it is also my sccm2012sp2 server. I'm trying to do an in-place upgrade. First I was hoping to upgrade the OS to 2012r2, then upgrade sql srv to 2014sp1 and finally upgrade sccm from 2012sp2 to sccm1511. The reason I'm trying to do all these upgrade in-place is to avoid changing sccm site name and dealing with new security cert.
The OS upgrade goes well all the way to the end, but after the last reboot the server gets stuck on the startup with a spinning wheel going for hours until I shut it down and revert to my snapshot. I tried uninstall wssus 3.0sp2, doing selective startup by disabling all non microsoft services, tried disabling all sccm-related services, tried uninstalling vmware tools, disabling NIC and deleting the NIC driver, but it always gets stuck after the last reboot.
Any suggestions are very much appreciated.
