I urge you to use 2.1.8 instead.

It only uses alphabetic directories for the mail spool if you set
hashimapspool: t

It will convert the index and header files.  You need to convert the
mailbox list yourself.

Strictly speaking, you shouldn't need to do anything with cvt_cyrusdb
unless you are specifying non-default backends for any of the databases
(you might want to consider skiplist for your mailbox list database, but
the mailbox list database can still be converted using ctl_mboxlist -d and
ctl_mboxlist -u anyway).

This isn't working because your paramater order is screwed up, you should
read the manpage (and specify an exact file to convert).

Lots of people have had success in a 1.x -> 2.x upgrade.
