Moving a local save to a dedicated server

[YankelMyWankel]

Is it possible to move a local world to a dedicated server world? If so is there a guide? I've been playing off my computer but would like to host it on a dedicated poweredge server i have in my basement ....

Also how are colonies that are offline protected from mobs?? I'm assuming then if all owners / members of a colony are offline mobs leave them alone? I'd hate to come back and find my colony destroyed because i was offline and my friends were on....

TIA!
