As noted in the documentation, using app ID is recommended where suitable. This does not, however, mean that you can't use also service accounts, as having an app ID registered does not mean that you'd be running in app-only mode.

We do not have any specifics on the detailed differences or impact of having app id or not

Hi Vesa,

My query is related to migrating content to SPoL using service accounts and an OTS migration tool.

I would like to know why Microsoft recommend us to use appID registration and traffic decoration if you are not clear on the differences/benefits/impacts?

Also, please can you confirm if there is a difference/reduction in throttling if an access token is used to make API calls to Azure? The migration app claims that this reduces the throttling MS applies to SharePoint migration activities.

Thanks

You get best possible performance and capacity when app-id is used with the decoration.

Using access token does indeed reduce throttling in the migration cases or in general.
