I am trying to convert a term set column to either a text or number field. The list column was poorly designed and should have been a numeric or single line of text field in the first place. The column currently forces the user to select an item from the term store, "1" - "9999".
My first thought was to make a new column of the correct type and use the CSOM to copy the values over from the bad column to the new column. Then delete the bad column. However, this will set the "Modified" and "Modified by" columns to me. Since I'm not changing the data, just the way it's represented on the site, I would like to find a solution to this that doesn't affect the "Modified" and "Modified by" columns.
