No, you don't need to do anything to enable uuid storage.
What might be confusing/surprising you is that no existing mailboxes are
moved to uuid storage at all, until you relocate_by_id them. But new,
top level mailboxes (e.g. new users) that you create after the upgrade
are created in uuid storage. (This is why the create brand new
mailboxes hierarchy -> copy files -> reconstruct trick worked.)
There is a new option "mailbox_legacy_dirs", which turns *off* uuid
storage /for newly created top level mailboxes only/. That is, if you
enable "mailbox_legacy_dirs", then any new top level mailboxes will be
created in the legacy storage instead of the uuid storage. This still
has no effect on existing mailboxes: existing mailboxes will remain
wherever they were, and new submailboxes are always created wherever
their parent is. You can always move mailboxes to uuid storage using
relocate_by_id, regardless of your "mailbox_legacy_dirs" setting.
It's usual in Cyrus for directories to be created as they're needed, and
not until. I don't know that this is definitely the case for the uuid
directory, but it is consistent with how we usually do things. Given
that you haven't created any new users since the upgrade, and the
mailboxes that already existed will stay where they are until you
relocate_by_id them, and any new mailboxes your existing users create
will be in the same place as their existing ones, it is not surprising
to me that there would not be a uuid directory yet on most of your servers.

Thank you Ellie. That is very useful information.
So do you think the problem several of us are having with relocate_by_id
not apparently doing anything is because we need to create the base
mailbox in uuid and THEN run relocate_by_id to move the emails and
sub-folders to the uuid storage?
For example, should we be do these two steps to move foo@xxxxxxxxxxxx?
1. Use cyradm to create the base mailbox, foo@xxxxxxxxxxxx. Assuming we
haven't set mailbox_legacy_dirs, this should create the uuid storage for
the base mailbox. This of course assumes cyradm lets us create it and
doesn't complain about the mailbox already existing (in old storage).
2. Use relocate_by_id to move foo@xxxxxxxxxxxx emails and subfolders to
the newly created uuid storage.
I think we have several test mailboxes on our dev server that I might
try the above on.
