BO system copy by promotion management tool : What to export?

HI,

Background

We want to move BI 4.0 SP 4 system to another machine by System copy.We want to use promotion management tool.

( We have installed BI 4.0 SP 4 on target system with same ports, same file system location as that of source system )

Question;

From system copy point of view, what kind of data we should export from source system?

( I can see users, folders, application, etc available for export ) If I choose all for export, will I be able import file in Target system successfully?

Regards,

Vinay.
