Migration from Google Apps: any hints, tips, recommendations?

I want to share this https://www.skykick.com/success-stories/snp-technologies on a 5000 user Google to O365 migration that may provide some insights.

Thank you Deleted looking forward to do it again soon :)

Also here are some tips on what does and what does not get migrated with the BitTitan tool: BitTitan

What migrates and what doesn’t for Google Mail\Vault to O365 migrations https://community.bittitan.com/kb/Pages/What%20items%20are%20migrated%20with%20MigrationWiz.aspx    

• Google Apps: Inbox, Folders/Labels, Email, Muted Email (as regular email), Contacts, Calendars (including links for Google Hangouts within calendar meetings).

o    Note: Links for Google Hangouts are a new default feature added to Google Meeting. Microsoft Office 365 doesn't have the corresponding property to map. Therefore, when migrating to Office 365, the links for Google Hangouts are added to the beginning of the meeting description body text on Office 365.

• Google Drive: Folders, Shared Folders in your Drive, permissions, Google Apps native files except Google Forms, Code Files (Xml, cs, cpp, h, etc.), Documents (docx, doc, odt, csv, pdf, etc.), Images (png, jpg, etc.), Executables (exe), Videos (avi, mp4, etc.), Audio Files (mp3, wave, etc.). Typical Destinations: OneDrive for Business, Google Drive.
• Google Sites: Files on Google Sites that are of the "File cabinet" page type can be migrated using MigrationWiz to SharePoint Online document libraries. The migration includes both documents and document permissions.​
• Google Vault (Source Only): Folders, Email
