Synchronize Components after RootElementName change

Question

I've changed the Element Root Name of my Schemas and now I want to synchronize my components with their new Root elements.

I'm trying to do it with the CoreService.SynchronizeWithSchemaAndUpdate method. Defining Flags like this:

SynchronizeOptions options = new SynchronizeOptions();
options.SynchronizeFlags = Tridion.ContentManager.CoreService.Client.SynchronizeFlags.FixNamespace;
options.SynchronizeFlags = Tridion.ContentManager.CoreService.Client.SynchronizeFlags.RemoveUnknownFields;
options.SynchronizeFlags = Tridion.ContentManager.CoreService.Client.SynchronizeFlags.ApplyDefaultValuesForMissingMandatoryFields;

And calling:

CoreService.SynchronizeWithSchemaAndUpdate(comp.Id, options);

But it crash giving me this exception:

Unexpected root element: Content. Expected:uuid:fe3b0600-5bfd-4224-b9ef-63c99bbb854e:MiceHPContent.

In this case, old Element Root Name was "Content" and I've changed it for "MiceHPContent". The SynchronizeFlags.FixNamespace flag it shouldn't to fix this problem precisely?

Here its defininiton from http://docs.sdl.com/LiveContent/content/en-US/SDL%20Tridion%20full%20documentation-v1/GUID-9E83FE0C-F650-451F-BEB3-7960A4925D90#docid=GUID-2B44D2F8-65E9-40DD-8408-DF1537BE50F5&filename=GUID-2B44D2F8-65E9-40DD-8408-DF1537BE50F5.xml&query=&scope=&tid=&resource=&inner_id=&addHistory=true&toc=false&eventType=lcContent.loadDocGUID-2B44D2F8-65E9-40DD-8408-DF1537BE50F5:

If the namespace of the content item's root element is not the same as the Schema's, it is set to the Schema's.

How can I synchronize the components?

Thank you.

Answer 1

You are not adding the flags together (using |= for instance), but rather overriding it every time.

Try it like this:

options.SynchronizeFlags = FixNamespace | RemoveUnknownFields | ApplyDefaultValuesForMissingMandatoryFields;

Answer 2

If all you've done is change the root element name, then you could fix them with a fairly simple XSLT, or by loading the XML into your favourite kind of DOM object and manipulating the nodes. A simple core service script would suffice for the task.

To be honest, it sounds like you're tackling it in the wrong order. There's no need to change the schemas before you've figured out how to update the content.

A late answer, but there is now an Alchemy tool to automate this process: https://www.alchemywebstore.com/plugins/Component-Synchronizer
