You can now use a new
Public Site Content Migration App to copy pages, documents, images, navigation, and
more from your existing website to your new website in Office 365.
If your Office 365 account was recently upgraded, you’ll notice that you
end up with two public websites.The
Public site (middle) is your current website and the
New public site (right)
is the new website introduced with the upgrade. With both websites
available, you can take your time learning how to use the new website
and upgrade websites at your own pace. Or, if you’re not using your
current website, then don’t upgrade at all.
To start the upgrade, go to the new website and install the
Public Site Content Migration App. (Choose
Settings > Add an app select
SharePoint Store and search for
Public Site Content Migration App.)
Once you install it, open the app on your new website. (
Settings > Site contents > Public Site Content Migration.)
Follow the instructions, which starts with installing the migration app
on your existing (pre-upgrade) website then returning to the migration
app on your new website to finish. (Your existing website must be
upgraded to the latest version of SharePoint before you can install the
migration app there.)
When you’re finished migrating content and customizing the new website,
you’re ready to switch to the new public website. You do this in two
steps. First, make the website public so that everyone can see it. (You
do this from the new website itself.)
Then, you change the website address (URL) of the new website so it uses your custom domain name, (like
www.contosobistro.com). This assumes you own a custom domain name; if not, then there’s no additional step here.
