It is ok if you don't change anything (or nothing significant) between version 1 and 2. But then, why would you rewrite from scratch ?
In any case, if you use a different team to rewrite your application, you just lost the biggest value of the previous team: experience solving that problem the first time. No amount of documentation can really make up for the difference . The source (with doc) of a software is a compiled version of business/technical knowledge of the team that developed it and not really that good as a guide to the next team.
Why not? Professionals knowns their tools much better, so they will made better choices in every aspect of project. If you place restrictions on their tools, they will work less efficient, unless you are already professional developer.

Of course. They will ask questions, so somebody from first team should respond to them.
