See the Site Templates section of the ODM Administrators Guide for an up to date list of supported site templates.
To verify the SharePoint template in use in your source SharePoint site the following steps can be used:
Connect to Office 365 SharePoint PowerShell and run the following script:
Get-SPOSite | ft url,template
The template can also be viewed by following the steps below:
Followed by the string will be the SharePoint Template ID (e.g., "webTemplateConfiguration":"STS#0"). ODM will support the discovery and migration of the templates mentioned above.
Note: ODM will not create a new site collection based on the Group#0 template. The corresponding Group or Team site must already exist on the target for the migration to be performed. Before trying to migrate a Group or team site with ODM SharePoint, use ODM Teams to migrate the team or create the Group or Teams site on the target using the O365 Admin console.
