HYTERA DMR - The easy way to change a Hytera code plug in minutes

When you say new CPS, what version are you refering too?  Only 7.xx?  I have 5.xx and 6.01 versions and the file extention for a code plug is "rcd" not "rcdx". I have a PD782G and do not have CPS 7.xx . Will this trick work on these versions of codeplugs and CPS or only on the newest codeplugs/CPS?
