Lisa is correct. Look to your Operating Agreement first and if the Agreement is silent on the issue, your State's LLC Statute should provide the answer to your question in the default rules/provisions.
In terms of switching states, most States will have the process you need to follow on their Secretary of State's website (Corporations division). Look on both State's websites for guidance. Also, if you are reasonably comfortable reading statutes, the State's LLC statutes will also give you direction.
Hope that helps.
