I don't think it makes sense to switch unless you plan on doing a large amount of transactions that will cut into your profits in a meaningful way. In which case, I'd ask why you are doing it that way. If you just want to sell, sell your stocks, pay the commission, and be done with it. You may end up paying to transfer, there will be a time frame in which you may not be able to trade, and it's often more hassle than it's worth.
