Microsoft 365 considerations
The server extension cannot be installed in Microsoft 365. However, it is highly recommended to install the extension on your on-premises SharePoint servers when migrating to or from Microsoft 365.
Microsoft 365 to on-premises
When migrating from Microsoft 365 to an on-premises destination, the extension can help to maintain certain values and allows you to use Insane mode.
On-premises to Microsoft 365
When migrating from an on-premises source to Microsoft 365, the extension can help to maintain certain values and will help package your information. Packaging your information can improve migration performance, which can reduce the strain on Microsoft 365 and potentially lower throttling.
