metadata migration

[ErikBart]

Hi,
We are moving files from on premise SP 2010 to SharePoint Online.
In the on prem library we are using managed metadata, I'm trying to map the source field to the destination and tryed a lot of different options, none work.

1. Source is field X of Type Managed metadata, destination is field X (same name) and Type Text. Check boxes are applied. Error is given that data types don't match.
2. The check boxes tell me that a new Text field will be created (both checked). So I select the source field X en no destination field. Error is given that there should be a destination field selected.

Can you give me a hint?
Thanx,
Erik

Tool works great though when using plain and simple source and target and default metadata mapping!
