How to move test cases to a different folder using VBA?

Hello.

We are required to do a massive cleanup of our huge test case repository (tens of thousands of tests). In order to do this, the retired/obsolote tests are to be moved to a different archive folder.

I had initially thought of extracting an excel report with Test Names and IDs, and running a VBA script, assuming that a move method exists in the API. But found that there is none for test cases.

Is there any way to do this progmatically? I do not have delete rights for any ALM items. So copy and delete is not an option.

Any help is much appreciated.
