Hi,
What are the types of UPGRADE(Sytem)
Thanks in advance
The SAP upgrade technology offers two upgrade strategies:
downtime-minimized and resource-minimized.
Choose the strategy that is best suited to your SAP system and to your requirements concerning system availability. Your decision depends on two factors:
1.Maximum permitted downtime
2.System resources
Characteristics of Upgrade Strategy Downtime-Minimized:
1.Parallel operation of production system and shadow system
2.Higher demand on system resources
3.Shorter downtime
4.Import of the substitution set into the shadow tables during production operation
5.Modification adjustment of the ABAP Dictionary objects during production operation
6.Activation and distribution during production operation
Characteristics of Upgrade Strategy Resource-Minimized:
1.Operation of production and shadow system only possible independently of each other
2.Production operation stops before import of substitution set into shadow tables or, at the latest,before shadow instance is started for first time.
3.Increased downtime
4.No ICNV

Are you talking about resource minimized and downtime minimized?
