ERP Upgrade 2-system landscape
Kindly asking your guidance in the following query.
What would be the best approach and the steps in a 2-system landscape (DEV,PRD) upgrade (ERP 2004 to ERP 6.0 EHP5, Win 2003/MSSQL 2005), to be able to achieve dual maintenance?
Any pointing to useful documents/blogs/discussions would be very appreciated also.
Thanks and regards,
