Updating a field "_dlc_DocId" giving 'Access id denied'
I'm applying a template and when is on SiteFields updating the field "_dlc_DocId" (ae3e2a36-125d-45d3-9051-744b513536a6) is giving "Access is denied"
This internal field should be updated? How can I validate if this field can be updated or skipped?
The differences between fields are attributes Version="2" and the SourceID="1234567890", and is only updating the field because of this. I changed the code to remove the attribute "Version" for the "equalityComparer" between them to skip but since the SourceID is also different, is trying to update the field attributes. How can I validate for skipping this kind of field?
Instead of throwing an exception for this when giving "access is denied" should I validate the type of error and show a warning?

I end up getting the "Sealed" property of the existing field to check if I can update it.
web.Context.Load(existingField, f => f.SchemaXml, f => f.Sealed);
Hope this is the better solution
