Frequently Asked Questions
What causes the 'Updates to system roles is not allowed' error in SharePoint 2019?
This error typically occurs when the Import-SPWeb command encounters system-level roles or permissions in the backup file that conflict with the destination site's existing system roles, security policies, or farm configurations.
Can I use the standard Microsoft Community forum for SharePoint Server 2019 issues?
While you can post there, the standard Microsoft Community primarily supports SharePoint Online. It is highly recommended to use the Microsoft Q&A platform with the specific SharePoint Server tag for on-premises issues.
Is there a parameter to ignore security warnings during Import-SPWeb?
Using the '-IncludeUserSecurity' parameter dictates how permissions are imported, but bypassing system role updates entirely may require modifying the source site's permission structure before the initial export process.
