How to upgrade to Fedora Silverblue 37 Beta?

How I can test and upgrade to Fedora Silverblue 37 Beta without a new installation of the whole OS?

Can I rollback it back to Fedora 36 Silverblue, if I am not satisfied with the Beta?

Thank you.

This is probably a good reference even thought it was written for F36.

An post about Fedora Silverblue 37 Beta will be published soon (hopefully) [Review and Publish] How to rebase to Fedora Silverblue 37 Beta

Thank you.
But If I play around a while with the Beta and I pin the previous version, what’s about the updates for Beta (new grub entries)?
What’s about the number of the unpin command (from where does it come, how it works)?

The pinned entries will stay in place. The updates will be deployed.

I.e. I’ve pinned 36.20220902.0
