Thank you, Timo, it worked but without underscore, that is, "select 'Y' 
as nopassword...".
But after that I have another problem:
---
dovecot: Jul 01 17:38:50 Error: IMAP(seriv): Corrupted transaction log 
file /mail/var/dovecot/seriv/.Trash/dovecot.index.log: hdr.size too

(imap child killed many many times).
I stopped dovecot, deleted dovecot.index files, and this problem was 
gone. But tags also were gone. Is there a way to upgrade preserving tags 
and other flags?
