Does a project using CodeReviewer transition seamlessly to Collaborator?

If a small development team starts using CodeReviewer with a project on a trial basis, and is eventually satisfied enough with it that they decide that it's worth investing in Collaborator for company-wide use, how seamlessly will they be able to continue working on the original project after upgrading to Collaborator? Will there be something special that they need to do to export the project's data before the upgrade, or can they just install Collaborator and continue as though they had been using Collaborator with the project all along?
