Hi Gurus,
I am in the process of implementing the upgrade project and would like to have your valuable inputs to achieve the completion of project.
Technical Details :
Source System : ECC 6 /NW SPS 9 with Kernel 700
OS : Windows 2003 & DB : MSSQL Server 2005
3 System Landscape
Target System : Upgrade to ECC 6 with EHP 7 ( Abap Stack)
New OS : Windows 2012 & New DB : MSSQL Server 2012
I have already gone through Recommended guides & Sap Notes/PAM where it mentions that we need to upgrade the OS /DB to either Windows 2008/2012/2014 and Sql 2008/2012/2014. I am also aware that NW SP patch level is one of the pre-requisite for the DB Upgrade.
In my current scenario , We are going with OS/SQL 2012, and one of the per-requiste as per the note 1651862 , NW Sp should be upgraded to SPS26.
My Approach will be as follows,
I will be using 2 Systems .as POC before stepping up into current landscape.
System A : - Build a system copy using production database same as source system in terms of SPS ,Kernel ,DB etc and perform SPS upgrade and take the patch level to SPS 26 .
System B : - New System will be with Windows 2012. Will perform system copy using system A and then upgrade MS SQL Server 2005 to 2012.
Once done , will go for EHP7 direct Upgrade ( ECC 6 SPS 26 to ECC EHP7 SPS 11)
Please correct me ,if I am wrong with the above approach.
My real question ,
Can I Upgrade directly to EHP7 without NW SPS 26 Upgrade ( All in on single step). Below approach
1.System Copy using old production data on New Windows 2012.
2.Upgrade SQL Server from 2005 to 2012.
3.Direct Upgrade using SUM in one single shot NW SPS 26 , EHP 7 SP 11 & NW 7.4 .I am getting confused because I generated stack file from my solman system and it took all required upgrade stack . Attached screenshot.
If I go with above approach will it work or any issues will come during upgrade.
Please Note as per Sap note 1651862, you should first upgrade sps before upgrading sql server 2012 .
Regards
Asim
