As an administrator, you can migrate an existing blog from one context to another, without restriction.
For
example, you can migrate a space blog so that it becomes a group blog. You can migrate from any context to any other context. When you migrate,
all of the blog's posts and settings will move to the destination context.
Note: Keep in
mind that migrating a blog to another context can change how the blog will be
managed and administered after it's migrated. For more information, see Managing Blogs.
On the Admin Console Blog Management Migration page, select the blog you
want to migrate.
Under Destination, select a destination:
To migrate the blog to become a system blog at the global level, select
the System Blog check box.
To migrate the blog into a space, under Communities Without Blogs
select the space you want the blog to be in. The list is limited to
spaces that don't have blogs because a space can only have one
blog.
To migrate the blog into a project, under Projects Without Blogs
select the project you want to migrate to. A project can contain only
one blog.
To migrate the blog to become a user blog at the global level, under
Users Without Blogs enter the user name for the person whose
blog it should become (you can also browse for the user name). A person
can have only one user blog.
