1. Create a New Workflow.  Set it to be a business process.
2. Add a "Move Entry" activity to the Workflow.
   1. Rename it to "Copy Entry".
   2. Select "Copy" and "Starting Entry".
   3. Set the Destination to "%(Entry Path)".
3. Add a "Rename Entry" activity to the Workflow.
   1. Set it to use the "OutputEntry" from the "Copy Entry" activity.
   2. Set the new name to: "%(Entry Name) (COPY) - Created by: %(Initiator) - Timestamp: %(DateTime)"
4. Add an "SDK Script" activity to the Workflow.
   1. Rename it to "Remove Highlighting".
   2. Set it to use the "OutputEntry" from the "Rename Entry" activity.
   3. Select "C#.NET" as the scripting language.
   4. Here's the full script:

      namespace WorkflowActivity.Scripting.RemoveHighlighting
      {
          using System;
          using System.Collections.Generic;
          using System.ComponentModel;
          using System.Data;
          using System.Data.SqlClient;
          using System.Text;
          using Laserfiche.RepositoryAccess;
      
          /// <summary>
          /// Provides one or more methods that can be run when the workflow scripting activity is performed.
          /// </summary>
          public class Script1 : RAScriptClass104
          {
              protected override void Execute()
              {
                  using (DocumentInfo di = new DocumentInfo(BoundEntryId,RASession))
                  {
                      List<AnnotationBase> anns = (List<AnnotationBase>)di.GetAnnotations();
                      foreach(AnnotationBase ann in anns)
                      {
                          if (ann.AnnotationType == AnnotationType.Highlight) Annotation.Delete(ann.EntryId,ann.PageNumber,ann.ItemId,RASession);
                      }
                      di.Save();
                  }
              }
          }
      }

   5. Add an "SDK Script" activity to the Workflow.
      1. Rename it to "Remove Sticky Notes".
      2. Set it to use the "OutputEntry" from the "Rename Entry" activity.
      3. Select "C#.NET" as the scripting language.
      4. Use the same script as the last item, but change line #23 to use "AnnotationType.Note" instead of "AnnotationType.Highlight".

Here's a document I made to test, with several annotations added in the Windows Client:

And here's the copy made by the Business Process Workflow (with the highlighting and sticky notes removed - but the stamps and redactions still in place):

I borrowed from this post for the script.
