Need Help - Yahoo Small Business Mail migration to New Control Panel

[WhiteFluffyPuppy]

Dear Babiato Tech Geniuses,
I need your help. I am trying to migrate a few dozen email accounts from Yahoo Small Business (Verizon) to my new hosting account.
It is proven difficult as migration keeps failing. Does anyone have any advice or software that can achieve this, please?
Thank you.

Thank you for your suggestion. I found different software. There's been improvement, but I still experience some challenges with uploading to the new server. Is the mailstore on Babiato?
