This is messy stuff to do. There are ways you could make Dovecot behave identically to UW-IMAP (mail_full_filesystem_access=yes), but for future and for security it's better if you don't do that.
I did not copy the old ~/.mailboxlist file to ~/mail/.subscriptions file, but notice some users have the latter file now. These are all mbox folders on the old and new server.
Copying it for users who haven't already readded their subscriptions would be a good idea.
Over the years, some imap accounts had their folders directly in their home directory and the contents of the .mailboxlist file would have an entry with just the name of the folder in it (Trash, eg), and most had the folders in their ~/mail folder with an entry like "mail/Trash". Our webmail app, Horde/Imp, always seemed to take care of this. If I create the .subscription file for the users during the move to the new server, should I move the folders to the mail directory and amend their .subscriptions file to reflect that change on these odd ball accounts, and will that affect how their client is seeing these?
Yes, move all of the mboxes to mail/ directory. With the compatibility namespaces it should work so that clients don't notice changes:

There are also a few old mailing list threads detailing all kinds of issues and solutions related to UW-IMAP -> Dovecot migration..
