EDU Tenant - File Migration for OneDrive for Business

Hi Calvin,

It sounds like you want to migrate a bunch of content from a fileshare server, right?  Our University was in a similar situation over the summer and found ourselves without much help in merging two Edu tenants.  If you are moving content from a fileshare, though - that would be much more straight forward.

Here are some suggestions:

• There are third party tools that can help automate much of this.  I highly recommend https://en.share-gate.com/ for this - it is affordable, reliable, and the team at Sharegate have great documentation.  I honestly can't say enough great things about this product.
• You'll need special permissions to access your users OneDrives.  It's much more than just being a global admin or SharePoint admin, and if you have a lot of users, you'll want to give yourself plenty of time to grant this access even using powershell.  Here's some instructions for scripting that:  http://www.jijitechnologies.com/blogs/add-remove-secondary-site-collection-admin-to-all-onedrive-for-business-users
• Make sure to open a case with Microsoft to request an exception to throttling.  If you don't let them know you are migrating a lot of content, you could be waiting a lot longer than you need to be.
• It's going to take longer than you think.  It just is.  ¯\_(ツ)_/¯

Best of luck, and happy to answer any questions that I can!
