We could really use a solution/tool to migrate D365 Marketing from one tenant to another. While I am aware of the current documentation and processes, this requires a lot of manual work and results in data loss.

Ideally, we could migrate everything - emails, pages, images, files, analytics, reports, etc - from one environment to another. Whether this be through a tool, a Microsoft support request, or a third-party application - doesn't matter.

Current information that I am aware of:
