what does it mean : Everything is alright but the schedules are not being picked up ?
do you see the schedules and they do not run or you do not see schedules ?
How exactly was the CMD DB copied ?
CMSDBCopy process in CCM is the best one.
Connection itself has nothing to do with schedules, scheduling information is located in the CMS DB.
You need to be on the last available XIR2 patch to ensure most bugs related to scheduling is fixed.
