As Ellie has written this option was removed a long time ago.

So to restore your mailboxes.db, I would do the following.

0. stop cyrus.

1. create a list of all mailbox names and positions on the filesystem.
    (e.g. by using "find . -name "cyrus.header" )

2. rename the imapspool (aka "partition-default:")
    and recreate an empty "imapspool" directory with the same owner/permissions


3. delete the mailboxes.db (we want to start with a empty mailboxes.db)

4. start cyrus so that only you can access cyrus via cyradm

5. create the folders via cyradm

6. verify that the list of newly created folders matches the position
    of the folders created in step 1.


7. stop cyrus


8. move the new imapspool with empty mailboxes away,
    and move the old imapspool moved in step 2 back

9. run "reconstruct -r -f user*" and "reconstruct -v max  user*"


10. start cyrus
