Upgrading R / 3 4.7 system to ECC6.0 with EHP4 along with windows 2008

Question

Hi All,
I am looking for your feedback about the plan for upgrading our Landscape to ECC 6. with EHP4 from R/34.7E.
Current Environment: R/3 4.7X110 with SQL 2000 in 32 bit windows 2003
Planning to upgrade to the level of : ECC6.0 with EHP4 64 bit windows 2008, SQL 2005 Database
Based on the previous experience in upgrade I have planned in the following ways.
Since my basis component is in the level of 63, its possible for me to restore the SQL 2000 database in SQL 2005 (Using System copy tool )
Step 1: Migration of OS / DB using system copy tool (R/3 4.7 with SQL 2005 in 64 bit Windows 2003 ), Then will leave the system for testing for some period and after the confirmation, planned to start the upgrade
Step 2: By meeting all the prerequisites, Planned to upgrade to ECC6.0 with EHP4 on the OS / DB upgraded system.
Step 3: Once the upgrade completed / With the confirmation from the functional and technical consultants, I planned to upgrade the windows 2003 to windows 2008 using system copy tool.
Note: I am not using SQL 2008 - Project decision.
The above mentioned plan is the only way(proper way) for doing such activities or is there any other way to shorten the project.
I should not ask the below question (Even after reading PAM and SAP note 1054740), But kindly regret me for asking this one, out of own curiosity, i am asking the below one.
1. Is there any possible to install SAP R / 3 4.7 in windows 2008 with 2005 (This will help me to shorten the project). I am completely aware that SAP wont support R/3 4.7 with windows 2008, if its not at all possible is there any other work around for me to shorten? Let me know your suggestions and thoughts
Your valuable inputs will help me to proceed further with the plans (I surfed the SDN and read master guides already) . I really want to make sure , the way which i am going is the right one.
Thanks and Regards
Vijay Kumar

Answer 1

Hi Jitendra,
Hope you should check the PAM again , Its supported for sure and also for upgrading to EHP4 - SQL 2005 is the Prerequiste.
Hi Abhi and Others,
Thanks for all your support.
I have successfully completed the project for my landscape and it was a great success too.
As you all said, since I had the hardware availability and time frame as well. Hence, I have tried both the possibilities.
Note :I would prefer and stick with the SAP proposed and supported way and even for my project I have followed the same. So I would recommend to stick with SAP supported one.
But for the own technical interest I have tried the other option as well which is not supported by SAP and also faced some typical issues as well / but solved on my own with some tricks and other activities. So, this option is also possible but highly risked one and of course(more importantly) which is not supported by SAP. So, i would recommend to go with the SAP recommended way.
Thanks for everyone and I am closing the thread
Regards
Vijay
