What is Dual Maintenance?
Keeping two development lines synchronized during a project, for example production support and the S/4HANA project landscape.
Changes made in the old landscape must be retrofitted to the new one. Retrofit tools in Solution Manager or Cloud ALM help, but manual effort is common. Missed retrofits cause regressions after go-live.
