Options for automated G Suite (Google Apps) to O365 migration?

I'm looking for an easy way to migrate a small company (50 email accounts) from G Suite to O365. I need to migrate mail, calendars, and contacts. If it would migrate distribution lists that would be a nice bonus, but not a requirement. I can handle all of the setup for DNS, etc. I'm just looking for a tool that will automate the actual box by box migration. I've seen both applications and websites that claim to be able to make it quick and painless but I'm hoping to get some recommendations from those who have actually done it. Most users have less than 10 GB of emails but I would like the calendar to go back as far as possible.
