Internet speed - Time Warner Internet

This question is about "Internet speed", with Time Warner Cable internet and apps. With the shift to Spectrum from TWC I notice that the starting internet speed is now up to 60Mbps, My question is because this is the starting speed will the current TWC customers that now have less than 60 Mbps be upgraded to the higher speed at no charge automatically or is it back on the phone with TWC to ask them to upgrade?

This topic covered Internet speed, and TWC cable internet service.
