RE: BW Upgrade 7.0 -> 7.3
in the near term is a project in which we upgrade our BW system from version 7.0 to 7.3. It will migrate all existing data and stack be but the stacks should be seperate.
Now, I raises the question what should I do.
Currently we have a dual stack installation. We want to separate the two stacks.
What’s with the DB? Will be installed on a separate server or on the ABAP stack?
Here are a few points to planning:
– Installation/Upgrade BW 7.0 –> 7.3
– Splitting of the dual stacks
– 2-3 SUSE Linux Enterprise 11 (64bit) server
– Migration of DB and all data files
– After splitting, migration of the stack (ABAP + JAVA) on separate servers
Since I want the existing DB and stacks (separated) still use makes me wonder if I just a pure SAP installation on the BW7.3 Servers do and then start the migration, or what should I do otherwise.
Is there BW 7.0 & 7.3 installation guides and a migration guide from BW 7.0 –> BW 7.3?
Experiences and opinions I would be happy.
Hopefully creates a lively discussion.
Thanks and best regards
SAP Landscape Transformation deals in general with consolidation and split of SAP systems / applications
However – your described case (split of dual stack while upgrading from SAP BW 7.0 to 7.3) is not a scenario covered by SAP LT software but should be covered with standard SAP Netweaver upgrade / installation tools. You may find more detailed guidance in respective upgrade guides located at SAP Service Marketplace: http://service.sap.com/instguides.
