imapsync is creating mailboxes in the namespace as long as they contain
UW: /home/jorey/archive/reports/mail (mail is an mbox file)
What's missing is that imapsync doesn't create archive & reports as
mailboxes (which may be the correct default behaviour, based on
UW-IMAP's response). I want to find out how to translate these
directories to mailboxes either in imapsync (if it's an option I've
missed), or after the transfer with Cyrus.
By switching to Cyrus, I'm adding the ability to store messages
alongside subfolders. After the migration, they still appear as part of
the mailbox heirarchy in the client, but behave very differently than
new folders that are created with Cyrus (the old UW ones are greyed out
in Thunderbird, for example, and cannot hold messages, only subfolders).
They are also completely absent from the heirarchy in webmail (using
squirrelmail), and there seems to be no way to make them appear, other
than recreating the entire heirarchy under a temporary name, moving the
messages, deleting the old parent, then renaming the temp parent to the
old name. My users will be confused when these parents fail to appear in
webmail, even though the children do.
After the migration, the only thing distinguishes these old UW
directories is that they contain no cyrus.cache, cyrus.header, and
cyrus.index files. Is there a way to force the creation of these files
if they are missing in a directory?

I wish I could. Sadly, this is not possible with UW-IMAP. These are
directories on the filesystem, and they can contain only mbox files
and/or subdirectories. There is no way to store a single message, as is
possible with Cyrus or Maildir. This is a limitation of the mbox format,
which stores multiple messages in a single file.
