Limitations

SharePoint 2010 has hardware and other limitations:

1. SharePoint 2010 will only be available in a 64-bit version. This change is not limited to servers. Developers running on 32-bit hardware will need new machines.
2. SharePoint 2010 will require a 64-bit version of SQL Server 2005 or 2008 (2000 is no longer supported).
3. Not all applications written for SharePoint 2007 will work in 2010. Certain APIs will be no longer be available. Others will be deprecated.
4. The basic flow for many tasks as changed. That, coupled with the laundry list of productivity-enhancing features means that any 2010 deployment should be accompanied by training for users, administrators, and developers.
