HELP

I have a phone Yealink T28P with firmware version 2.61.0.80 and want to upgrade to the most current version of Firwmare 2.73.0.50. I understand that I must gradually updated as versions but do not know the sequence firmware versions, either the firmware page tells me I can update directly. Thank you for your cooperation.
