The first step is to clean out any morph data that may have come from your donor (actually at some point you want to clean out the rig donor, which is why people call them "Blank CR2s").  This morph data is never any good, even JCM data, because the vertex count and vertex order of your new model has nothing to do with the donor.  It's all garbage and needs to go.

Morph data can appear in every body part block.  Parameter dials linked to morph channels also typically appear in the BODY, sometimes in other body parts besides. The morph data blocks are located in each body part (usually only in the body parts they affect) and prefaced with "targetGeom".  The parameter dials that control them from the BODY are in the BODY block and are prefaced with "valueParm".  They are all named with an Internal Name as well as a Name, like bones are - Internal Name and Name may not match (for DAZ-origin morphs they usually don't).

JCMs (joint controlled morphs) are also sometimes controlled by chunks of code in individual body parts; I don't do it this way in my conformers but other people might - I don't really look at how other people do things too much, but it's good to be aware of.

Also, any material configuration from the donor needs to come out.  These are towards the end of the CR2 in the "figure" block, and are prefaced with "material".

ps: this is the really nasty part, if you have a plaintext editor.

oops: nobody really puts these steps into their tutorials as far as I've seen, because it's ridiculously hard with a plaintext editor (sorry if I keep repeating this) and impossible to boil down to step-by-step.  If you have a CR2 editor on the other hand it's going to depend on which CR2 editor you have.
