Changing the Server Collation

Changing the default collation for an instance of SQL Server can be a complex operation and involves the following steps:

  • Make sure you have all the information or scripts needed to re-create your user databases and all the objects in them.
  • Export all your data using a tool such as the bcp Utility. For more information, see Importing and Exporting Bulk Data.
  • Drop all the user databases.
  • Rebuild the master database specifying the new collation in the SQLCOLLATION property of the setupcommand.For example:
    /SQLSYSADMINACCOUNTS=accounts /[ SAPWD= StrongPassword ]

  • Create all the databases and all the objects in them.
