What are the challenges one may face when migrating from a 6500 to a Nexus 7000? I guess part of the answer is that it depends on where the 6500 is positioned in the enterprise. For example, if it is being used at the WAN edge with the Flex Wan module, the Nexus poses a problem because it does not support any legacy serial/OC WAN linecards. All it supports is ethernet.
On the other hand, if the 6500 is being used at the aggregartion layer of a data center and has switched modules deployed (FWSM, CSM, etc), the challenge when migrating to the 7000 will be that the 7000 does not support such modules and separate appliances must be used instead.
Is there a comprehensive overview document that anyone may know of that elaborates on such a migration in terms of a stargtegy, challenges, considerations, etc?
