Fatal error: Call to undefined function system_run_automated_cron()

Since you moved the DB over, did all the tables get created correctly? Check for the system table for a row entry with the name column set to "system". Is the status column set to 1?
Does modules/system/system.module exist and is executable by the webserver?
