I think ShareGate is the only tool with these kinds of content migration features. Other tools are more complicated or costly, but ShareGate hits the sweet spot. It gives me a nice user experience for moving data between shared drives and SharePoint, SharePoint sites, OneDrive and SharePoint, and MST and SharePoint. I think data migration is its best feature, and restoring permissions in bulk works well. I also like that I can install it on a server so multiple people can use the same machine to do their tasks.

Ease of use and implementation.. It's been invaluable during our M&A of other companies

I like that ShareGate is easy to use and low cost. Its on-premises and cloud permission mapping makes file migration much easier, and its pre-migration check for on-premises file shares fixes problems before migration. It also moves the process from manual work to automation. The initial setup was easy for IT professionals.
