Jiriteach:
Even better - just sign up with your new ISP and they will ask for you existing details (account number) etc. Things are automatically cancelled on the 2degrees end.
I recently did this and it was all automatic.

You do not even need to deal with LSP (losing service provider)
I would always recommend you contact the LSP to tidy up the account and ensure it is closed.
When I worked in a call centre, a lot of calls were generated from people who signed up with another RSP who advised that they would close the end customers account with the LSP. Unfortunately, this isn't the case. Never has been and probably never will be.
While a transfer of services should typically stop any billing related activities, the account usually won't be closed unless you ask for it to be.
Something to also keep in mind is if the new RSP connects you on a different port on your ONT. This isn't a transfer, so no alert is generated. Same goes for DSL, if you're connected on another pair instead of a straight transition.
