ECC 6/MS Windows Server 2008/SQL Server 2008 Upgrade

59 Views

I am working with a client who wishes to do an ECC upgrade from ECC 5 to ECC 6. They also wish to upgrade the Op System from Windows Server 2003 to Windows Server 2008; and the database from MS SQL 2005 to MS SQL 2008.

My proposal is to Upgrade ECC, then the Op System then the DB in each environment before moving forward. We would do the first upgrade in Sandbox to determine timing, issues, etc. We would create a production support path to be used during the project, then start the upgrades Dev-QA-Prod.

The client has said that this is a risky approach and that SAP recommends a 2 step process, that is, upgrade ECC 6 thru all environments and then go back and do the Op Sys and Db upgrades afterward.

In my mind my approach is less risky as we will ensure each environment is clean and functioning smoothly before moving forward; there is less intrusion to the end user; testing is only accomplished once in each environment. The actual production build would be split over 2 weekends, app upgrade first then op sys and db.

The assistance I need to understand isu2026.does SAP have a recommendation in this case? I have not seen anything that says not to do the single step process I am recommending.

Thanks for any support you can provide.
