Cluster implementation - Migrate Server or Migrate APP&a

I’m in the early stages of setting up a clustered Integration Server environment. We currently have a stand-alone 6.1 Integration Server. I’m wondering, once the clustered environment is up and running, should I take my existing server and have it join the cluster, or migrate all of my existing packages, adapters, services, etc… to the new environment. Any thoughts or suggestions would be appreciated.

I asked the same question once, and the answer I received from WM was that it was more advisable to migrate your packages/code/etc to the new cluster.

Dont forget to patch!
