Change in keypair with which instace was created

Hi,

I have around 40 instances created with one keypair. Now there is a requirement to rotate the key. Request guidance on any possible options to change the keypair with which the instance was created in openstack to use a new one without doing a rebuild.

Thanks,

Adding to the question, if the solution is to update a new key to all the servers, is there anyway to attach the new key to openstack setup as it still points to the old key.

Thanks,
