I sure did! I'm on 2020.2.1 right now. It's running now ok. I had an error towards end of the install that said this during the install:
Upgrading Flow Database
POSTGRES UPGRADE FAILED. NETFLOW WILL NOT WORK. PLEASE CONTACT SUPPORT.
This was in all RED CAPS. I do have a case open. I'm not using any netflow from SEM... actually I wasn't completely aware it did netflow...
PKI, CAC, and tokens doesn't seem to work and isn't really documented anywhere. In some places it says it's supported but I don't see any real documentation on how to get PKI and CAC or token logons working in SEM. I would think two factor authentication would be a high priority for an SIEM.
