I have followed the migration guide at the following url:

http://www.manageengine.com/products/ad-manager/help/getting_started/configuring_mssql_server.html

However, when attempting to migrate the db to MSSQL I have found that the ChangeDB.bat file is missing from our ADManager Plust installation.

Please assist if possible, please do not hesitate to request further information. 

Kind regards,

Dean
