Preparing for Sharepoint 2010: Importing your old sharepoint 2007 sites

A look info the future, don't be afraid, migrating your old 2007 sharepoint sites can be imported into the new Sharepoint 2010..... but what will happen when importing 2007 sharepoint export files (.cmp* files) into the new 2010?

When you upgrade Sharepoint 2007 to 2010, by default the layout will stay like it is in 2007, but this setting can be changed:
Go to Site Actions > Preview New Visuals, choose one of the 3 new options:

1. Keep the previous Sharepoint user experience (default)
2. Preview the new Sharepoint 2010 user experience, but let me return to the previous user experience
   => allows you to flip between the old and new experience and prevents you to do something that isn't compatible with the old version
3. Use the Sharepoint 2010 user experience and don't ask me again
   => you can do things that are incompatible with older versions

Things to remember from previous posts:

• Your servers (development, production, everything!) need to be 64bit!
  Sharepoint 2010 won't run on 32bits anymore (read more)
