No, you'll get a message when you connect that the client is out of date and it will prompt you with a download link for version 2.5 of the VI client. You can have both versions installed at the same time should you have a need for that, but I'm not sure if that is supported or not.
excellent, that was my 2nd question, running a number of different virtual environments (for political reasons) here, and my 2nd question was about to be, can u run both client versions...
