5.4 How to migrate SQL Server 2000 databases
WinCC projects that were created with versions prior to WinCC V6.2 SP2 include database
settings of the SQL Server 2000.
To access databases with SQL Server 2014 that were created with versions prior to SQL
Server 2005, you must change the compatibility setting.
To do so, use the SQL Server Management Studio up to maximum SQL Server 2008. You
connect
the
database using the *.MDF file, change the settings and remove the database once
again.
Edit all databases that are part of your WinCC project:
● Databases in the local WinCC project
● Distributed systems: Databases on all PCs of the WinCC system
● Databases on the file server
● Databases on an archive server
● Swapped-out databases
Requirement
● You have created backup copies of the databases in the WinCC system.
Back up the associated *.LDF file for each *.MDF file.
● The SQL Server up to version SQL Server 2008 is installed on the PC.
