None of the new features work with TPM 1.2. As stated, 2.0 is NOT backwards compatible to 1.2. They are two totally different devices.
A new or current install of 6.7 on a server with 1.2 will work the same as 6.5. You just won’t be able to take advantage if the new features. If you are using HyTrust then it will continue to work. I think we added something to 1.2 for them but beyond that, No change
Thanks for the clarification Mike!
