I am not sure if this is the place to ask this.

I was wondering what was the preferred method of bringing my ZFD
workstations to ZCM.

Should I create a master ZCM image and just drop that on to the existing ZFD
stations? How would handle the old image safe data or would I be better to
install the ZCM agent on the existing ZFD stations and then allow them to
import into ZCM and then re-image them with my new ZCM master?
