How to find report specification change history

[dust0000]

Hello,

We have auditor need to find out report specification change history for this year. Cognos report include some report run history. Here is my question:
1) is there a way to only query report specification change history not include report run history.
2) We have BSP metamanger installed but after we upgrade the metamanager not configure to C10. Can any expert help me on this configuration?
3) BSP metamanger is not working for old system because we change the old system url from reports.123.com to oldrpts.123.com

Thank you very much in advance!
Best regards.
