Child installation points will get automatically upgraded if they have replication enabled. You need to manually upgrade installation points which have replication disabled.
If you want to check whether an installation point has replication enabled, or if you want to know the current version of an installation point, navigate to the installation point page (image).
Download the latest installer of Miradore Management Suite from https://support.miradore.com/WebSites/Authenticated/sp_Downloads.aspx.
Run the installer on the installation point host.
Select "Upgrade an existing instance".
Check connection details and continue with Next.
Finish the installation.
