If you upgrade to fios from an existing DLS installtion (with verizon) there should be NO termination fees of any kind. (I actually upgraded from verizon DSL to Fios with no issues)
However, if you have a year left on a contract for your DSL, you may be required to sign up for at least a year or more for FIOS (a period equivalant to your existing contract at minimium).
