What are the best ways to say "Goodbye X, Hello Y" in Ancient Greek?
Context: I want a snappy phrase to ring in the new year, saying Goodbye 2022, Hello/Welcome 2023!
I was going to use χαῖρε for hello but it seems that it can mean both hello and goodbye, and could be ambiguous in this phrase...?
The exact era or dialect of Greek is not so important, just that if a modern Greek speaker heard it, it would be noticeably ancient-sounding and not modern.
Bonus points for short and easy to pronounce. Greek letters and transliteration would be most helpful.
