Stefan Gossner posts about running PRESCAN.EXE against a Windows SharePoint Services (WSS) 2.0 database before upgrading it to WSS 3.0, and also provides a link to download the tool so you can run it ahead of time.
What does this have to do with DPM? Well, if you're using DPM 2007 Beta 2, you can protect WSS 2.0 databases as SQL Server databases. However, if you upgrade WSS 2.0 to WSS 3.0, you need to reconfigure protection of the data as Windows SharePoint Services data.
The procedure (which is also documented in the DPM 2007 Operations Guide, in the chapter "Managing Protected Servers Running Windows SharePoint Services", available in the download section of the Connect site) is as follows:
- Create a recovery point of the WSS 2.0 data that is protected as a SQL Server database.
- Stop protection of the data, choosing the Retain replica option.
- Upgrade the server running Windows SharePoint Services.
- Add the upgraded Windows SharePoint Services farm to a protection group by selecting it as a Windows SharePoint Services data source.
Data in the retained replica remains available for recovery, but it is not associated with the upgraded Windows SharePoint Services farm.
