Selective Message Retention in PI

Dear All

We have a PI production instance where the messages are persisted for 15 days using the parameters in NWA (xiadapter.inbound.persistDuration.default/xiadapter.outbound.persistDuration.default)

We are going live with some new critical interfaces and business wants the related messages to persist for 30 days

These new interfaces are ICO based and in the advanced parameters there is an option to persist them using local configurations, but there is no option to select the duration

The question is how can we persist the messages for these new interfaces for 30 days without changing anything in the current interfaces where the message retention is for 15 days
