Change datasource location

All my reports are using odbc connection to connect to database.
Anytime database server is changed I have to manually update the
datasource in each report. My question is there a better way to do
this?
Thanks in Advance,
Bhavnawhat version of crystal u r using?

Using front end interface u can set datasource..|||I am using crystal 10. I know how to update datasource in the report. What I would like to know how to update all the reports datasource at one time instead of opening up each report and changing the datasource.

Thanks!sql
