Having created a Next-gen project and linked it to a Confluence space; what is the prevailing wisdom with regard to setting permissions in the Next-gen Confluence space? Should groups be created (not required for Next-gen projects) for easier maintenance. Or, simply give the administrator for the Next-gen project, permission in the associated Confluence space for adding users etc... ?
Using groups would be easier for run-support maintenance and if one had to migrate to classic... well the groups would already be setup...
