T. Rowe Price telling me to do initiate 401k rollover via withdrawal

Hello, Long story short I got an email from an old employer saying that they were no longer using T. Rowe Price for their 401k and that I will need to move my funds. I contacted T. Rowe Price and they said in order to do a 401k rollover (into another traditional 401k) I would need to do a withdrawal. I was always under the impression that a withdrawal is a taxable event whereas a 401k rollover, assuming it's one traditional account into another, is not. Has anyone rolled a 401k out of T Rowe Pri
