Microsoft have stated that they cannot gaurentee that there will be no more database schema changes between Beta 2 and RTM and as such there is no upgrade path from Beta 2 to RTM.ÃÂ This leave the TAP and the PEP participants in a bit of a hole in that they have signed up to having sites live by the time SharePoint 2010 goes RTM.
Jie Li on his blog has stated that
If you are exporting/importing content that means you are "migrating". It would be fine. However attach a beta content database to RTM will not work.
So canÃÂ it beÃÂ confirmed that I can use the deployment API to export content from say a Beta 2 site and again using the deployment API can import that content into a RTM site.
In realityÃÂ I would use Chris O'Brien's SharePoint Deployment Wizard which uses the deployment API.
