The production downtime is the period during the technical upgrade when the production system is out of service. The downtime period depends on various factors such as hardware power and size of the tables to be migrated, and is therefore contingent on each individual situation. SAP upgrade technology provides you with two strategy options: downtime-minimized strategy and

Resource-minimized strategy.

Characteristics of the downtime-minimized strategy:

Shorter production downtime

Parallel operation of production system and shadow system that enables the execution of as many upgrade tasks as possible during the uptime of the production system

Higher demand on system resources

Characteristics of the Resource-minimized strategy:

No parallel operation of production system and shadow system

Lower demand on system resources

Increased production downtime

SAP recommends that you perform the upgrade using the downtime-minimized strategy if a short production downtime is required.
