Checklist for SCCM 1802
• Ensure that all sites run a version of System Center Configuration Manager that supports update to 1802
• Review the status of your Software Assurance or equivalent subscription rights
• Review installed Microsoft .NET versions on site system servers
• Review the version of the Windows Assessment and Deployment Kit (ADK) for Windows 10 : The Windows 10 ADK should be version 1703 or later. (For more information on supported Windows ADK versions, see Windows 10 ADK.) If you must update the Windows ADK, do so before you begin the update of Configuration Manager. This ensures the default boot images are automatically updated to the latest version of Windows PE. (Custom boot images must be updated manually.)

• Review file and data replication between sites
• Install all applicable critical updates for operating systems on computers that host the site, the site database server, and remote site system roles
• Disable database replicas for management points at primary sites
• Set SQL Server AlwaysOn availability groups to manual failover
• Reconfigure software update points that use NLBs
• Disable all site maintenance tasks at each site for the duration of the update installation on that site
• Temporarily stop any antivirus software on the System Center Configuration Manager servers
