[Former Member]

Dear All:

I need to upgrade R/3 4.6(MS SQL 2005) to ECC6(MS SQL).

But i don't know how to do.

I may need to use VMware to make a simulation first.

Can anyone tell me how to do it step by step?

or any usefull documents.

More clearer and easier.

Thanks...

Hi,

I can just give you a overview how the process will be, you have to check the upgrade guide. It has given in detail.

Generally upgrade process will have

1. OS Upgrade

2. Database Upgrade

3. SAP component Upgrade

i. SAP PREPARE Phase

ii. SAPup Phase

4. Post upgrade procedures

In PREPARE Phase we will define all the parameters, path of the upgrade medias, create new tablespacecs. We have to solve all the issues raised in this phase, If complete this face sucessfully without any error. There is 70% chance of going with smooth upgrade process

In SAPup phase actual component upgrade will happen, in the initial stage a screen will appear stating like

'Continue with options selected in SAP PREPARE Phase" Yes/No

Its recommended to select yes. Here only we will define the upgrade strategy(Downtime Minimized or Resource Minimized).

After completing the SAPup phase, check the upgrade guide no. of post upgrade steps are there to perform.

Hope it helps

Look for the Combined Upgrade and Unicode Conversion Guide. This gives the process for going from 4.6 to 6. Don't even consider skipping the Unicode conversion, it'll only come back and bite you later.
