Any Daedalus wallet experts?

I moved my funds out of my old Byron wallet into the new Shelly wallet. I can’t remember but when that happens would I have been given a new backup 24 word phrase? My old backup was 12 words which I have. When I moved to Shelley do I need to find the 24 word phrase to recover my funds?

I have input the 12 word phrase but that just opens up my old wallet. Any other options?

When you created the new Shelley wallet at Daedalus you got a new 24 word phrase.
If you want to restore that wallet you need to have that 24 words
