You would certainly see similar results. Although some people don't see a VIN for a few weeks after switching. But many are getting a VIN right away if you have an order old enough that they are finished fulfilling MYP orders for that OD. You will see an EDD change within a day or two.
There are a number of ways to make the change...you can call Tesla or text or online chat. If you want to do it yourself you can try and use this link
www.tesla.com/teslaaccount/edit-design/RN##########
Use your unique RN # at the end. That URL works but sometimes is finicky and takes entering it a few times. I typically log out of my account, enter the URL, login, click on my car on the Dashboard page and then enter that URL again. I also found I needed to keep the "RN" part capitalized for it to work.
One final way to do it yourself is going in and changing your method of payment to Finance instead of Cash. This will make your account "incomplete" and give access to the Edit-design link...edit your design and then switch back to cash. I haven't tried that method but a number of people have done it that way.
