Migrating tasks from one account to another

Daniel Westerdale 

Hello there, thanks for this thread, I am having a serous problem here or maybe I'm just too scared to try it and potentially mess stuff up.

We are already using Microsoft ToDo App (via the Windows10 App via Windows10 Store) with e.g. a personal so-called Microsoft Account being the email address of a user curently.

This user has plentiful of objects in the Microsoft ToDo App, lot of lists, ToDo entries there and a good history and extensive work put into this ToDo account.

Then recently, the decsision was being made, that the mail/domain and the company is buying a Microsoft 365/Office 365 product, so this email address of the user currently being regarded of the type "Microsoft personal account" is going to end up as a user-name inside the Microsoft365 ExchangeOnline product etc.

What happens with all the objects/entries in the currently personal-kind of account when this accounts ends up as a microsoft365 account?

Do the ToDo objects/items end up magically inside the microsoft365 product as well? do I lose all these ToDo objects as this account (via its name=email-address) gets re-created as new/fresh/empty inside the microsoft365 concept?

Would really like to know, as this is some serious data loss for a number of users here. Also the export conecpt of Microsoft ToDo via logging-in with this account/credentials into outlook.com kind of doesnt give me any answers at all to, on how to possibly import this kind of data into a different/new todo/account at all?

People speak about the need to re-create everything that is inside ToDo, but as the email address = way to login to the ToDo App, I can not even switch between two ToDo Accounts as far as I understand, and to make copy/paste over the stuff here either.

What to do now or how do I need to understand these situations and concepts? Thanks a lot for a speedy answer to this matter.
