How to update outdated Data Warehouse data?

I am cloning my IBM Collaborative Lifecycle Management (CLM) solution from production to staging server. I have cloned the machine with CLM applications and all databases, including Data Warehouse database. Due to some reason my data warehouse data is not up to date.
How can I update Data Warehouse data on cloned system to have up to date data there?
