Now that we have seen how to create sites,
what about updating them? Sites can be
updated via the Admin Center or
PowerShell, and you can change quite a few
things such as the title, URL, hub
association, and more. To update sites via
PowerShell, we used this Set‑SPOSite
PowerShell cmdlet, specified identity of
the site that we want to modify, and then
all of the different properties that we
want to change. Remember that a lot of the
settings that we can change are only
available via PowerShell and not visible
inside the Admin Center, so most of the
time, I always prefer to do it via PowerShell.
