You can install Symantec App Center (on-premise) in a single-tenant mode or multi-tenant mode. The multi-tenant mode was originally limited to SaaS installations and this feature is in beta for on-premise installations.
Multi-tenant mode for on-premise installation is not considered supported at this time and customers can only proceed at their own risk. We would advise waiting until this feature is an officially supported where documentation and support will be available.
For more information, see Deploying Symantec App Center after installation.
