Data Loss
The original release of this build from 2018-10-02 has a bug that deletes every file in the My Documents, My Music, My Pictures, and My Videos directories when updating from older versions of Windows Server 2016. Back up all data before upgrading or disable the "Delete user profiles older than a specified number of days on system restart" group policy prior to installation.
