A commonly requested feature in VMware Cloud on AWS (VMC) is the ability to rename an SDDC. Currently, it is not possible to rename an SDDC after it has been deployed. On Friday, an update was made to the VMC Service to introduce a new VMC API (Tech Preview) that will allow customers to rename their SDDC. The API is just the first step and our UI folks are already working on adding this natively to the VMC UI which I actually got a sneak peak of just a few days ago.
UPDATE (02/11/19) - The ability to rename an SDDC is now also available within the VMC Console UI, so you can use either UI or API to perform this operation.
The new SDDC rename API is very straight forward to use, you simply perform a PATCH operation the specific SDDC /orgs/{orgID}/sddcs/{sddcID} which includes a payload containing the updated name. Below are three ways in which you can easily rename your SDDC, including a UI method for those that want to quickly rename an SDDC and not have to write a single line of code.
