Note also that when the upgrade option is set to import, the associated full-text indexes are rebuilt if a full-text catalog isn't available. Depending on the amount of data being indexed, importing can take several hours, and rebuilding can take up to ten times longer. If the upgrade option is set to import ( upgrade_option = 2) or rebuild ( upgrade_option = 0), the full-text indexes will be unavailable during the upgrade. However, if a SQL Server 2005 (9.x) database has full-text indexes, the upgrade process either imports, resets, or rebuilds them, depending on the setting of the upgrade_option server property. Typically, the database becomes available immediately. If you restore a SQL Server 2005 (9.x) or higher database to SQL Server, the database is automatically upgraded. You must retain that certificate used to encrypt the database encryption key for as long as you need the backup! For more information, see SQL Server Certificates and Asymmetric Keys.įor additional considerations for moving a database, see Copy Databases with Backup and Restore. To restore an encrypted database, you must have access to the certificate or asymmetric key used to encrypt the database! Without that certificate or asymmetric key, you can't restore the database. For more information, see Back Up a Transaction Log (SQL Server). Under the full or bulk-logged recovery model, before you can restore a database, you must back up the active transaction log.
