1. We are going to migrate our production server to a new server. Right now we are running on Win2K, MS SQL 2000...
Enterprise and R/3 Enterprise 4.7X110. What is the best migration method?
2. We'd like to upgrade our OS on a new server to Windows 2003 and let the other servers remain in our landscape to win2K, i.e.QAS-DEV. Is this the recommended method?
You will need a new SAP license key as the hardware will change. If you subscribe to the SAP Pro Journal, you might want to take a look at the article I wrote in the May/June 2003 issue, titled "Database System Copies Made Easy".
2. It's recommended that you upgrade all of your systems to the same OS. Start with either your DEV or QAS box. Then, do the production system. Having the same OS on all systems guarantees full compatibility. Also, you won't have unpleasant surprises. Take a look at SAP Note #710079 -- R/3 no longer starts after you upgrade to Windows 2003 -- as an example of what I'm talking about.
