What are the key benefits of migrating data to OneDrive?

Let us look at the top 3 benefits when using the OneDrive sync client:

1. Be productive and stay connected
OneDrive migration enables you to synchronize your content to your PC and Mac so you can easily and securely access files anytime—even when you are offline. Once you're back online, your new files and edits will sync to OneDrive automatically. You can view and edit your files, as well as collaborate in real-time and share files/folders easily and directly from your desktop—without using a web browser. Also, everyone who has access to these files, will always have the latest version of the file at hand.
OneDrive also allows syncing IRM-protected files and supports differential sync (currently for Office files and rolling out to ALL file types), that saves time and bandwidth by only syncing parts of files that have changed, rather than re-uploading the entire file. All of these scenarios are also supported in virtualized desktop environments.

2. With more files, comes more space
As you create and collaborate on more files and take more photos, do you worry whether there is enough storage on your device? You shouldn’t have to—OneDrive has your back!
OneDrive Files On-Demand on PC and Mac helps you access all your files in OneDrive without having to download all of them and use storage space on your device. You don’t have to change the way you work, because all your files—even online-only files—can be seen in File Explorer or Mac Finder.

3. Access beyond your individual files and folders
We see OneDrive as the files app for Microsoft 365 enabling you to access all your shared content across Microsoft 365, inclusive of SharePoint and Microsoft Teams, in addition to your individual work files. OneDrive enables you to sync files and folders from shared libraries that you have access to within your organization harnessing a ubiquitous and secure productivity experience across OneDrive and SharePoint. You can also sync files from libraries or folders that have been shared from other organizations (B2B). This implies, that you can sync content shared not only by peers within your own organization, but also by partners, customers, external contractors, suppliers and third-party vendors outside of your organization that you regularly collaborate with.Two quick notes for admins on B2B sync-
Azure Active Directory (AAD) guest accounts play a key role in making B2B collaboration possible.
A guest account at one organization links to a member account at another organization. As a result, a single sign-in to their account enables access to content from their own organization and from any other organization that have created guest accounts for them.
