We have implemented a new vCMP instance on a 2400 and that is running successfully on 11.2.1. We are reasonably happy with V11 on a VIPRION , although I agree about the need to have a more control over resource allocation. We are now migrating from 1500 and 6400s to vCMP and thinking about how to migrate the configuration from 9.4.8 to 11.2.1 ( via a test F5 running 10.2.4 ) . Anyone any experience /comments on migration especially how to handle the move from 'real ' interfaces /vlans to virtual interfaces and VLANS on vCMP?
