You do not have to make a new will: wills are not state-specific in the way you mean. Yes, each state has its own criteria for *creating* a will in that state, but every state is legally bound (e.g. by the Constitution) to respect and enforce valid wills from other states. Therefore, as long as the will was properly created in the state where it was made, it is valid everywhere else in the country. The law does not require that the lawyer drafting your will ask for your ID; a failure to do so does not invalidate it either.What you describe is accordingly not legal malpractice.
