Accidentally changed Switchover date to 2023 when it was meant to be 2022, what can I do?

As the title reads, someone in our org changed the switchover date incorrectly and we lost an entire year's budget, is there a way we can revert this and salvage all of our information?

Thankfully we have an archived model but we have tons of connections written to this model and want to continue working in the one that is now incorrect, is there a way to get the info from the archived model into the model everyone uses?

@Misbah

Thanks in advance!
