Cannot change the properties of copied publishing page

Question

Hi all,
I have a requirement to copy a Publishing Page and modify some of its properties including Taxonomy/Managed Metadata field. I use SPFile.CopyTo() method and everything seems to be fine until I try to update the new page's properties:  they are not impacted.
Here is my code:
SPWeb web = SPContext.Current.Web;
SPFile file = web.GetFile(sourcePageUrl);
string desUrl = publishingWeb.PagesList.RootFolder.ServerRelativeUrl + "/" + newPageName;
file.CopyTo(desUrl);
SPFile newFile = web.GetFile(url);
newFile.CheckOut();
newFile.Item["TaxonomyField"] = string.Format("{0};#{1}{2}{3}", termWssId, term.GetDefaultLabel(CultureInfo.CurrentUICulture.LCID),
TaxonomyField.TaxonomyGuidLabelDelimiter, term.Id);
newFile.Item["TextField"] = Guid.NewGuid().ToString();
newFile.Item["BooleanField"] = false;
newFile.Item.Update();
newFile.Update();
