Rescheduling invites

Hey guys. Hope everyone is staying well during this stressful time of not only wedding planning but re-wedding planning as well. Wanted to know for those that are rescheduling how did you go about only inviting or re-inviting and notifying those guess that RSVPed yes? Like a nice way of saying “ this is only for you so don’t go telling the world our numbers are solid”. Granted I know some possibly couldn’t make the prior date but can make this one, but I can’t extended the invite unless I get declines based on budget, floor layout and added cost with this change.
