In a previous post I wrote about how you can migrate Microsoft Teams from one (source) Office 365 tenant to another (target) Office 365 tenant by using third party (3P) tools to ease and automate the migration process. BitTitan is one of the tools which can be used.
BitTitan published a White Paper regarding “Top Migration Considerations for Cross-Tenant Teams Migrations” which you can request and download to avoid typical pitfalls and get awareness on what limitations there might be. You can find the link to request the download of the White Paper at the bottom of this post.
