You can use the php please multisite to automate converting from a single to a multisite installation.
Defining Sites
To choose which sites the navigation will be available in, just make sure the file exists in the respective sites' directories as described below.
Folder Structure
The folder structure will differ from the single site structure explained in the navigation guide. Now, navs should be organized into the respective sites.
The tree array will also be relocated into separate files organized into sites. The meta level information will remain in the existing YAML file.
content/navigation/ nav.yaml site-one/ nav.yaml site-two/ nav.yamlA navigation will be considered unavailable for a particular site if a file doesn't exist in its subdirectory.
Trees
The navigation file itself will continue to be responsible for defining things like its name, route, etc.
The "tree" defines the pages and their layout. The tree is what is localized to each site.
# nav.yamltitle: Navroot: truecollections: - pages - articles# site-one/nav.yamltree: [...]# site-two/nav.yamltree: [...]
