When survival beta fully releases, will old survival be gone? If so, when and how will this happen?

survival beta will run for ~1 month at the same time as old survival

then old survival will close and beta survival will reset, becoming the new survival

so if i start now in beta my progress is still deleted?

So what will happen with old survival

it will get deleted/reste i think

btw DemonBoyOG, a player called WorldRuler21_ is griefing peoples bases from rtp and putting signs saying you did it (not targeting but just wanted to say)
