How to migrate a keyvault private endpoint to a new subnet

I have a private endpoint in a subnet that the operation team would like to reclaim. I have another subnet I can create a private endpoint in, but want to know the steps in replacing a private endpoint and if that requires any downtime for the keyvault service.

    Thank you for your post!

    I understand that you currently have a Private Endpoint that your Operations team would like to reclaim. You can create another Private Endpoint to replace this, but to account for any downtime when it comes to replacing/switching these two Private Endpoints, you'd like to know the steps to replace a Private Endpoint within the Azure Key Vault.

    Assuming you have a VNET, subnet in that VNET, and the correct RBAC permissions for the VNET and Key Vault - to replace a private endpoint within your Key Vault, you'll need to:

    1. Establish a private link connection to your existing key vault.
    2. Validate that the new private link connection works.
    3. Once you've confirmed that the new private endpoint is working correctly, you can remove the original private endpoint.

    As for downtime, it's possible that there may be a brief interruption while you're updating and testing the new private endpoint, but this should be minimal if everything is configured correctly. I'd also recommend trying to perform these operations during a maintenance window or low-traffic period.

    I've also reached out to our Key Vault engineering team to confirm this and will update as soon as possible.
