It depends on the classes, how they apply to the new program, and when and where they were taken. Some vo-ed schools have agreements with community colleges and universities to accept transfer credits, which can make the process easier. One school might be willing to accept a class from a vo-ed school while the next institution might now. Bottom line: if you plan to transfer eventually, make sure that the vo-ed classes are eligible for transfer. You won't want any surprises.
