Upgraded from MX Arenium 2004 to MX V8i - old schemes?

We have recently changed fromMX Arenium 2004 to MX V8i and have several old projects and models that we want to use in this new format.  It is just as straight forward as opening the project and the model file will come in, and all alignment data will be available, or do we need to do something first?  We still have one machine running the old program just in case!

 

Thanks
