migrate data from BI 4.0 SP7 to 4.1 SP2

Hi,

there are a lot of discussions and best practices about the update from 4.0 to 4.1 in the SCN. We have one BI 4.0 SP7 Server. I have a new 4.1 server installed to update the hardware and the operating system.

How can I migrate the data from the old 4.0 SP7 installation to the new 4.1 SP2?

Thanks
