How do I upgrade ReSharper 4.5 settings to ReSharper 5.0 settings

Question

I've recently upgraded my code from Visual Studio 2008 .NET 3.5 to Visual Studio 2010 .NET 4.0.

I've used ReSharper 4.5 and now I'm using ReSharper 5.0.

I want my ReSharper 4.5 settings (the ones in .resharper file) to be upgraded to ReSharper 5.0 settings.

Is there an automatic way to do it? Should I do it manually? Would just overwriting the .5.0.ReSharper file with the .4.5.resharper file do that trick?
