Well, in SDN you can find a lot of docs too...

I've passed to a Technical Upgrade (4.6C to 6.0), if you need other material or share experience... contact me...

Hi,

Following are the upgrade steps:

1.System preparation and stack level patch upgrade . Basis Team

2. SPDD Phase . ABAP and Functionals

3.Up gradation of the system . Basis Team

4.SPAU Phase . ABAP and Functionals

5.DBACOCKPIT for indexing . ABAP TEAM

6.Issue resolution and error tracking . ABAP and Functionals

7.Z programs corrections . obsolete function modules and objects

The Points to be remembered during an upgrade

. Before we start the up gradation project, during the pre upgrade study, We need to find out weather

there is any customer specific development done by SAP in the previous system (4.6c). If so, the

time to act is just after the pre upgrade study only. The customer would only want to retain the

customer specific module developed by SAP.

We need to get SAPfs intervention in the project before we start the upgrade. SAP would develop certain patches to be run on the previous system (4.6c) to capture all the customer specific development and then they would run some patches on ECC system . this would release the customer specific development in the new system (ECC). This is a very crucial and important check of the step. If not taken care of at the proper time, it might hamper the Customer Specific development on the new system.

. It is to be assured that the new system is at the latest stack level for ABAP, XI, BI etc before we start

the SPDD and SPAU phase

. Only one request is to be made for SPDD. For SPAU too, only one request should be made.

. Previous system sandbox (4.6c) should be available for reference during the entire upgrade project

and should not be scrapped before the Go Live.

Hope it will useful.

Thanks
