Changing plans

I have been a Comcast/Xfinity customer for the past 45 years. I am thinking about changing my present tv/internet package from Ultimate TV (which I guess is now called Premium TV) to the TV Plus package because I do not even use one-third of the 185+ channels in the plan. My current plan costs include: internet 300 mbps  which has a 5 year guaranteed rate until June 39, 2030, tv price which includes broadcast tv fees and regional sports fees and 2 tv adapters. The current plan also includes a $20/month 2 product discount for tv/internet packaged together. I already had paperless billing for this account and added autopay 2 weeks ago to the account which would provide an additional $10/month discount on my future bills. My question or concern is: "Will my present 5 year guaranteed rate ($65/month) stay the same and will the $30/month discounts I am presently entitled to for the 2 product discount and paperless billing/autopay be carried forward as discounts to the new TV Plus package plan?
