When selecting the profiles directory name at install time, the profiles directory should not be shared between 7.7.x and 7.6.x servers if the site uses custom user privileges on the 7.6.x server, plans to use custom user privileges on the 7.7.x server, and plans to keep the 7.6.x server running because changing a privilege (for any user) will cause the file to get rewritten in a new 7.7.x format which is incompatible with a 7.6.x server. If changes in privileges are expected after the 7.7.x installation, the files in the 7.6.x profiles directory can be simply duplicated to the new 7.7.x location to seed the 7.7.x location before the initial server start up.

Sites that have chosen to upgrade a 7.6.x server to 7.7.x, should also use the Web Console to edit and adjust the workspace manager name (used for the Web Console banner) in the Workspace configuration file to reflect the 7.7 release level.
