You may want to consult with your Arizona attorney before you move for many reasons (like issues of probation, etc.) but specifically for this reason as well.  It is most likely that if you maintain your Arizona license the requirement for the interlock will follow you.  In other words, Arizona may not clear your drivers record until all requirements are met. I would also contact the ignition interlock vendor as there may be issues with taking the equipment out of state. And no, you can not venue shop for a reduced sentence.  The courts in New York will uphold the decision and sentencing of the Arizona courts.  Get some advice here.  Good luck on your fresh start.
