The default mode. All source folders go to the same destination — either a single SharePoint library or a single user's OneDrive.
Use this when your migration has a natural single endpoint: "all these files go into the HR site," "all these home folders go into Alice's OneDrive."
For mixed destinations (some folders to SharePoint, others to OneDrive, different folders to different libraries), see Multi-Destination.
In the project Destination step, click Select Destination. You'll see a choice modal:

Pick SharePoint. CloudMove walks you through:

You can also create a new folder inside the picker if the destination doesn't exist yet.
Pick OneDrive. CloudMove lists all licensed users in the tenant.

Search by name or email and pick a user. Files land in the root of that user's OneDrive, preserving the folder structure relative to each source folder.
Picking OneDrive automatically switches the project to multi-destination mode with a single mapping per source folder — but you won't notice the switch in most cases.
Click Change on the configured destination to pick a different one. This doesn't affect already-completed migrations, but it will be used for the next one.
If you need different destinations per folder, see Multi-Destination. Otherwise, move on to the scan.
