There are a number of redirect plugins that you could use to do the redirects from within WordPress. The better ones allow you to specifiy the server code you wish to deliver (ie, 301, 302, etc).
My advice is to just do your due diligence and make sure the Meta data and titles, info arch, etc match what you had before, along with proper redirects, and you should be fine if not better than you were before.
