Alright..dove right in and decided to get my management cluster upgraded to 8 after getting pre-requisites upgraded such as vROps, LogInsight, vRealize Lifecycle Manager & NSX.
My NVME drives in the hosts are not on the VMware vSAN HCL, but thankfully was able to ignore that in the Remediate settings options. I do have TPM 2.0 chips with Host Encryption enabled, so far no errors.
Next steps will be to explore vSAN ESA..
