1. Create a query of the records with the attribute. NOTE : If building the query based off of the attribute, please ensure that you save and close the query. If there is any specific information you need from the output, export the results as they will update if re-running the query results after Step 2 and remove all results.
  2. Globally delete the existing attribute from the records in your query. NOTE : Recommend to create an output query with this as a backup query in case any issues arise with the query created in Step 1.
  3. Edit the attribute data type.
  4. Globally add the attribute to the records in your query.
