Hello

We have a site–subsite system developed using OpenCMS 10.5.1, as shown in the
attached snapshot. In our setup, nvs serves as the headquarters website, under
which nvs-school has multiple subsites.

We are planning to upgrade OpenCMS to version 19 and would like clarity on the
upgrade process for this type of structure. Specifically, should the
headquarters site and its subsites be upgraded separately, or can the upgrade be
performed for all at once?

As I am new to this, I would appreciate your guidance to ensure the process is
handled correctly.

Kind regards,
Nivedita
