The following article discusses the limitations associated with migrating ASPX pages with Insane mode to Microsoft 365.
For additional information on limitations associated with using Insane mode, see Migration using Insane mode with Microsoft 365 and on-premises.
- Classic pages
- Modern pages
SharePoint 2003 and SharePoint 2007
Migrating ASPX pages from SharePoint 2003 and SharePoint 2007 is not supported in Insane mode.
When a library contains an ASPX page, the migration of that whole library reverts to Normal mode.
Web parts not supported in Insane mode
Some web parts will not migrate using Insane mode. For example, any web part that is not included with your basic SharePoint package will not migrate using Insane mode.
A warning will be displayed in your Migration report when an unsupported web part is detected.
Note: Custom or third-party web parts are not supported by the ShareGate migration tool. They may migrate using Normal mode, but there is no guarantee that it will work.
Modern site page templates
Migration of modern site page templates is not supported using Insane mode.
When the library of a modern site contains a page template, the migration of that whole library reverts to Normal mode.
Note: Normal mode has its own limitations like list item IDs and unresolved users that are not supported.
Modern site page comments setting
The Comments setting is not preserved using Insane mode. The page at the destination will have the comments enabled by default.
Web part toolbar type
The web part toolbar type is only supported when migrating to Microsoft 365 using Insane mode.
