How to change DocumentType programmatically

I believe this is the right place to ask this;

I have a documentType A which I have copied to B (exact same properties),

where I would like to change about 500+ nodes of DocumentType A to B, programmatically, as using the GUI is not practical.

Not sure if Im using the right approach, trying the following saves the nodes (i.e. code executes) but does not change their document type;

Anyone can shed some light?

const int blogNodeId = 1289; // ROOT node where doctypes A are children.
 //Get the ServiceContext and the two services we are going to use
var contentService =     Services.ContentService;
var contentTypeService = Services.ContentTypeService;           
var contentType = contentTypeService.GetContentType(1273); // doctype B's ID
var blogNode = contentService.GetById(blogNodeId);
            foreach (var post in blogNode.Descendants())
            {
                if (post.ContentType.Alias == "blogArticle")
                {
               var content = contentService.GetById(post.Id);
              content.ChangeContentType(contentType); // this doesnt seem to do anything
                contentService.Save(post); // all parsed nodes are marked as saved
                                   // all works except .ChangeContentType
                }
            }

Hi, contentService.Save(post) should be => contentService.Save(content)`. You are modifying the variable 'content' but you are saving the variable 'post' at the end.

Hi Jivan

On the very same topic, after I change the document type via the code all seems OK on the backend office UI - i.e. I see the document type has been updated and icon reflects the corresponding to changed document type.

I have changed one node document type manually via the backend office UI, then run the code for the remaining 500.

When I try to iterate all the nodes from its main node with CurrentPage.Descendants("blogArticle")

there is only one item returned - the one I manually changed. No clue why the others are not returning as the document type seems to be changed. Published all.

If I change to code to CurrentPage.Descendants() then I get all of them.

Is there a step that I am missing? Would you have any ideas?

I would try checking the /app_data/Umbraco.config and seeing if the XML cache for your modified nodes has been updated correctly - that is, the modified nodes have the correct tags (the name of the new doctype) around them. If not - you need to rebuild the Umbraco XML cache (which is, or at least was, a very common Umbraco troubleshooting step). This can time out and/or slow down your site - so be careful on production sites.
