Updating a managed metadata column from choice column value

Question

I am trying loop through
all lists in a web, and for each list, 
1. create a managed metadata column->Working
2.
Pull value from choice column->Working
3. Move
choice column value to managed metadata column->Not Working
Point number 3 is not working. Please advise
Here is the code:
static void Main(string[] args)
//Pulling the rootweb of the Site
const string SPLocationListColumn = "CHECK6";
SPSite site = new SPSite("http://sp2010:8080");
SPWeb rootweb = site.RootWeb;
//Setting up the taxonomy terstore, termset and term
Microsoft.SharePoint.Taxonomy.TaxonomySession taxonomySession = new Microsoft.SharePoint.Taxonomy.TaxonomySession(site);
TermStore termStore = taxonomySession.TermStores["Managed Metadata Service"];
Console.WriteLine(termStore.Name);
Group group = termStore.Groups["KM Metatags"];
Console.WriteLine(group.Name);
TermSet termSet = group.TermSets["Document Classification"];
Guid termsetid = termSet.Id;
Console.WriteLine(termSet.Name);
Term term = termSet.Terms["Document subclassification"];
TermCollection terms = termSet.Terms;
Console.WriteLine(term.Name);//Looping through all webs of the input website
SPWebCollection collWebsite = site.AllWebs;
for (int i = 0; i < collWebsite.Count; i++)
using (SPWeb oWebsite = collWebsite[i])
//Looping through all lists in web
SPListCollection collList = oWebsite.GetListsOfType(SPBaseType.DocumentLibrary); ;
for (int j = 0; j < collList.Count; j++)
SPList list = collList[j];//if the list name is Documents, create a new field of MMS type
if (list.Title == "Documents")
Console.WriteLine(list.Title);
TaxonomyField field = list.Fields.CreateNewField("TaxonomyFieldType", SPLocationListColumn) as TaxonomyField;
field.SspId = termSet.TermStore.Id;
Console.WriteLine(termSet.TermStore.Id);
field.TermSetId = termSet.Id;
Console.WriteLine(termSet.Id);
field.AnchorId = Guid.Empty;
try
{//Add the newly added MMS field to default view
Console.WriteLine("Entering");
Console.WriteLine("Entering");
list.Fields.Add(field);
Console.WriteLine("Entering");
Console.WriteLine("Entering1");
SPView view = list.DefaultView;
Console.WriteLine("Entering2");
list.Update();
SPViewFieldCollection collViewFields = view.ViewFields;
collViewFields.Add("CHECK6");
Console.WriteLine("Entering3");
view.Update();
Console.WriteLine("Entering4");
catch (Exception e1)
Console.WriteLine(e1.Message);
}//Capture a choice field by name subclass and move it to the newly added MMS field
for (int f = 1; f < list.ItemCount; f++)
if (list.Title == "Documents")
Console.WriteLine(list.Title);
SPListItem item = list.Items[f];
if (item.Fields.ContainsField("subclass"))
SPField field9 = item.Fields["subclass"];
String subclassvalue = field9.GetFieldValueAsText(item["subclass"]);
Console.WriteLine(subclassvalue);
TaxonomyField taxonomyField = item.Fields["CHECK6"] as TaxonomyField;
TaxonomyFieldValue taxonomyFieldValue = new TaxonomyFieldValue(taxonomyField);
taxonomyFieldValue.TermGuid = term.Id.ToString();
taxonomyFieldValue.Label = subclassvalue;
taxonomyField.Update();
item.Update();
list.Update();

From here:
http://www.c-sharpcorner.com/uploadfile/anavijai/programmatically-set-value-to-the-taxonomy-field-in-sharepoint-2010/
taxonomyFieldValue.TermGuid = term.Id.ToString();
taxonomyFieldValue.Label = term.Name;
SPListItem item = list.Items.Add();
# item["Title"] ="Sample";
item["TaxonomyField"] = taxonomyFieldValue;
item.Update();
list.Update();
it appears you're missing the point where you assign that taxonomyFieldValue to the item's taxonomy field in question.
