Files Migration to Office 365 Sharepoint Online
We can narrow down the headache by using some 3rd party solution to migrate hundreds gigabytes files from our legacy file server to Office 365 SharePoint Online or One Drive for Business.
My Favorite tools are:
I prefer FilesToGo because it is more cheap for short term migration ( one or two month). But if you want to more advanced migration & syncronization between Sharepoint online & legacy file server, you can use Layer2 Cloud Connector.
Conclusion: Next year maybe I want to buy Layer2 Cloud Connector Professional because it is more flexible and more advance.
