I practiced a similar question about instance migration, and I feel like manually migrating to idle hosts could help with performance, but I’m not confident about its security implications.

Hmm, I'm a bit unsure about this one. I know SAML is used for authentication, but I'm not super familiar with the specific attacks. I'll have to think it through.
