Yep, Mitel has decided to implement their new pricing tool, CPQ. To me, it's ok, so far. My biggest issue is that I haven't been able to figure out how to import my Partner Parts List from SWB. My Partner Parts List contains my 3rd party parts and I have quite the list. I thought that there'd be a way to import a Parts List to a section of CPQ so that after selecting Mitel equipment, you could go to the Partner Parts List to select 3rd party parts and equipment such as telephone faceplates for analog telephones.
I'm aware of the Loose Items mode but I have so many 3rd party parts that it'd take me a day to enter the parts one at a time. I don't have the time for that. Another thing I noticed is that if I do enable Loose item mode on the Configuration page, select SX200 (Hospitality), the equipment that comes with the base hospitality package is not there. If I then click on the Results tab, I get a message stating my configuration contains no components. It appears as though I may have to choose the parts for the hospitality package a la carte.
SWB is toast. Upon logging into Mitel Connect, there's a bulletin that was posted today called Mitel CPQ:CPQ FAQ. The last page of that document outlines a SWB/CPQ Transition Plan (Channel Partners). That will answer your questions. The short answer is that SWB support will be terminated in 2/28/17.
Not sure if it's ok to attach the document to this post, so I will not.
