Retention Management on Standalone ILM Servers

Hi Everyone,

I wanted to know

if we can perform Retention Management by installing standalone ILM Servers(Retention Warehouse) and connecting them to Live ECC Application Servers?

Is the above approach feasible ? If yes how will ECC Live data be applied with ILM Rules ?

Currently the client has planned to build ILM Dev/Quality/Prod and later plan to use them to perform retention management for existing ECC Landscape.Is it possible ?

Regards,

Vasu
