dovecot - May 2011 - Crash test :)

I'm considering to move my mails from maildir/mbox to mdbox. One of my
doubts is: how can I restore my mails when something terrribly wrong
happens. 

I understand that I should use doveadm import "backup_location"
"mailbox" all.

So I try to import with:
 
doveadm -v import "sdbox:~/Mail/dbox-temp/spamcop/reports/"
"#Dbox/spamcop/reports" all

#Dbox namespace were defined as:

--8<---------------cut here---------------start------------->8---
namespace {
  hidden = no
  inbox = no
  list = yes
  location = mdbox:~/Mail/Dbox
  prefix = "#Dbox/"
  separator = /
  subscriptions = yes
  type = private
}
--8<---------------cut here---------------end--------------->8---

dbox-temp were defined earlier as 
--8<---------------cut here---------------start------------->8---
namespace {
  hidden = no
  inbox = no
  list = yes
  location = sdbox:~/Mail/dbox-temp
  separator = /
  subscriptions = yes
  type = private
}
--8<---------------cut here---------------end--------------->8---

1. when I specified for example sdbox:~/Mail/dbox-temp/spamcop/reports/ doveadm
search mails under ~/Mail/dbox-temp/spamcop/reports/mailboxes/INBOX/dbox-Mails/
- am I missing something from documentation?  
(I expected rather ~/Mail/dbox-temp/mailboxes/spamcop/reports/dbox-Mails)


2. when I move dbox-Mails to proper place I got:

doveadm(kjonca): Error: sdbox
/home/kjonca/Mail/dbox-temp/spamcop/reports/mailboxes/INBOX/dbox-Mails: Invalid
dbox header size
doveadm(kjonca): Error: sdbox
/home/kjonca/Mail/dbox-temp/spamcop/reports/mailboxes/INBOX/dbox-Mails: Invalid
dbox header size

And nothing were imported.

Notices:

a) there were only u.* files, no indexes.
b) u.* files were created on i386 system, and import test on amd64.

You probably want something more like:

doveadm import sdbox:~/Mail/dbox-temp "#Dbox" mailbox spamcop/reports

This isn't needed.

What Dovecot version? I think this is fixed already.

Index files use the same format in 32bit and 64bit systems (but not in little vs
big endian).

Um. :(  Files were created about 2 months ago. It was certainly 1.x, but
now it is hard to say, what exactly version it was.

But question is open: Can I (and how) restore mails from so old backup?
