Daedalus Byron Era 12 phrases to Yoroi

Hello. I have the following problem. My Daedalus Wallet is from the Byron period (12 Phrases). I would like to send my ADA to a current version, but a 15 or 24 word phrase is always required. Adalite.io didn’t work, it tells me to try via daedalus mainnet. But it takes forever here, I’ll take a few days! only at 70%.
I’m not a professional, is there a way to make the transfer easier or do I have no other option to access my ADA with a new wallet.
Thank you for your support
