How to change vault transit kms to aws kms

Hi, I have Boundary running in my production environment, and I am currently using Vault Transit KMS for keys. But I would like to switch to KMS AWS keys. How can I do this without losing the data I already have stored in Boundary? Is there a way or just starting from scratch?
Can anyone help me?

We do not currently have a way to perform key migration, sorry.

I understand. So the only way would be to start a setup from scratch?

Is there any way to extract the Boundary data, start a configuration from scratch with the AWS KMS keys configuration, and then re-import the data into this new configuration?

Just really to find out. If there is no way we will continue with KMS Transit.

I await a reply, thanks!
