Convert lookup type column to managed metadata type

​We currently have a library in SharePoint 2007 that takes the title of an item lookup; in SharePoint 2016, we would like to replace this with managed metadata using the title taken from the source lookup.  However,  ControlPoint provides the following error when attempting to map the source column to the destination column: "Exception: An error occurred during the operation of a service method: The given guid does not exist in the term store."

 

What is the best approach to mapping a lookup to managed metadata?  If that's not possible, what alternatives exist that allow us to preserve the column data in an automated capacity?

  • Hi!  This has worked for some of the libraries we're migrating, but for some reason we're still encountering the error with one column in one of our jobs. 

     

    Do the terms have to be implemented into the store already before the migration?  That would be a bit bizarre as the other columns seem to sense that the name already exists and appends a GUID to the term it's implementing (but that's the behavior we're witnessing), so we see two terms, "ThisIsATerm" and "ThisIsATerm_01234567-89ab-cdef-0123-456789abcdef", for which the suffix of the latter is the GUID of the former.  Did we miss something else?
