Consequences of changing a project license

I currently have a project on CodePlex that I licensed under the LGPL 2.1 license. This license information is added to the header of each file in the project.

I'm considering to change the license to the less restrictive MIT license, but I can't figure out the consequences of doing this. My main two questions are:

  1. Could changing the license (to the less restrictive MIT) affect any of my current users?
  2. Should only new code be published under MIT or can / should / must I change the headers of all files to reflect the new license?

Thanks for any advice.
