The Migration into CM would entail manually translating your non-default CDH configurations into cloudera managers configuration for CDH. There is not an automated way to do that.

Other than that, the CDH upgrade is documented, here:

As @Grizzly indicated, I would think you would do this in two phases: 1) install CM over your existing CDH cluster (see this thread), then 2) upgrade via CM to CDH5.
