Moved to new SGS5 phone and have all the info to transfer from old SGS3 EXCEPT I don't have the old phone IMEI. Never thought about it during the transfer. Do I now need to repurchase Pro license?

No need to pay again. You bought the license with PayPal, is it? You can login to your online PayPal account to see the information.
