Hi ranga91092 ,
According to Adobe, the recommended paths are:
Previous location | /etc/blueprints |
New location(s) | /apps/msm (Customer Blueprint configurations) /libs/msm (Out Of the Box Blueprint configurations for Screens, Commerce) |
Previous location | /etc/msm/rolloutConfigs |
New location(s) | /libs/msm/wcm/rolloutconfigs /apps/msm/wcm/rolloutconfigs |
Reference: Sites Repository Restructuring in AEM 6.4
For Clientlibs: You can move your project specific clientlibs to /apps and use allowproxy servlet recommended by Adobe.
Reference: Using Client-Side Libraries
No need to change the etc/map location.There is no new location recommended by Adobe for them.
