1. Connect to the database with SQL Server Management Studio (find server name in dashboard)
  2. Right-Click the database and select "New Query"
  3. Copy the replace script to the query editor
  4. Replace the variables "oldvalue" and "newvalue" with the values to be replaced
  5. Run the script - it will show which values will be replaced
  6. If the values look correct, uncomment the commented lines (everything below "execute replace") and run the script again
