If you already have a reservation at a Caesars property, from what I saw you can keep it, you'll just have to find transportation to LVCC via the monorail or other means.

Not sure on transfers. They have negotiated with Sahara on a rate and are looking to add more.

Forum servers are being overloaded, from DEF CON's homepage:

After a great 25 year relationship Caesars abruptly terminated their contract with DEF CON, leaving us with no venue for DC 32, and just about seven months to Con!

We don’t know why Caesars canceled us, they won’t say beyond it being a strategy change and it is not related to anything that DEF CON or our community has done. This kind of no-notice cancellation of a contract is unheard of in the conference business. The parting is confusing, but amicable.

TL;DR - DEF CON 32 will still be August 8-11 2024, but now held at the Las Vegas Convention Center (LVCC) with workshops and training at the Sahara.
