Restore pre-SP1 backups to an SP1 farm (SharePoint Server 2010)

  • Artykuł

 

Applies to: SharePoint Server 2010, SharePoint Foundation 2010

This article explains how to restore backups of databases that you made on farms before you installed SharePoint 2010 Service Pack 1 (SP1) to farms that have SP1 installed.

The SharePoint 2010 Service Pack 1 (SP1) upgrade process alters the schema of some farm databases and all content databases. Because of these changes, you might need to take additional steps to restore a backup that you made before the farm was upgraded to SP1 to the farm after it is upgraded to SP1. For more information about SP1, see Service Pack 1 (SP1) for SharePoint Foundation 2010 and SharePoint Server 2010.

Important

We strongly recommend that you perform a full backup immediately after you upgrade to SP1.
