Q : I have a plan to migrate SAP BW from Windows Server 2003 to Solaris 10.
Where can I find the documentation related to this activity ?

A : http://service.sap.com/systemcopy
Please be aware, that for a production migration you need to have a
certified migration consultant on site, otherwise you will loose support
for the target system, see http://service.sap.com/osdbmigration
Basically you export the whole database using R3load and re-import it
using a migration installation.
BW is pretty special, some additional steps have to be done before you
start the export (e. g. SMIGR_CREATE_DDL and more).
