If you are running a Fusion drive DO NOT UPGRADE to 10.13.2 without reading this page...
https://beta.apple.com/sp/betaprogram/apfsfusion
Unless you follow these instructions, your upgrade will fail and you may not be able to recover your mac from a Time-Machine backup.
Yes, I know Indigo server does not officially support 10.13. But, some people may have other machines, or may not have had problems with 10.13 and Indigo server.
YOU HAVE BEEN WARNED
