Removing RW6 after upgrade to 7

Have upgraded to 7 & am very happy. Now want to remove 6; I’d usually use CleanMyMac to uninstall software & wondered if it was safe to do this for RW6? It cleans out library files & preferences also. I presume from copying message when RW7 first installed that all my stacks/themes/plugins/snippets are now copied to a new RW7 folder & that removing everything related to RW6 won’t affect it?
Anyone tried this?
Thanks for advice.
