Hi, Suresh!

As this is a quite complex topic, you should probably consider attending one of the courses SAP is offering - like <a href="https://websmp201.sap-ag.de/~form/ehandler?_APP=00200682500000001337&_EVENT=DISPLAY&COURSE=ADM326&COUNTRY=BE">ADM326</a>.

A complex task it is indeed. To get you on the right track:

1. Download the upgrade guide relevant to your landscape; Architecture, database

(http://service.sap.com/instguides)

2. Study the SAP Notes referenced in the upgrade guide.

3. Order the SAP Going Live Functional Upgrade Check from SAP. (You are allowed two sessions free of charge - one before and one after the upgrade). This will provide information amongst other, whether your H/W is capable of handling the additional load of the new release.

4. Plan for H/W upgrades if necessary

5. Consider the effect of the upgrade on other SAP and non-SAP systems you have connected and which may be affected by the upgrade.

6. Plan and document the testing of your business scenarios

7. You will need to have installed SAP Solution Manager to perform the upgrade. This will give you the necessary upgrade key.

8. Plan for O/S and Database Upgrades

9. Carry out the upgrade in this sequence: DEV, Q/A, PRODUCTIVE systems.

The actual upgrade consists of two modules:

a) PREP - Can be run during productive operation and will perform initial checks of your systems

b) SAPup - This is the actual upgrade. You will need to choose between two strategies: downtime-minimized or resource minimized.

I find it very essential to create your own upgrade scripts with all the actions that need to be carried out before PREP, after PREP, before SAPup and after SAPup.

Good Luck
