dovecot - Jan 2019 - Moving messages between servers with different configurations

Hi Martin,

I feel a bit like an idiot, but I have been trying with copy, so I do 
not lose any message when testing. But I can't get them to copy. I do 
indeed have same uid and gid.


[@~]# doveadm mailbox status -S 192.168.10.43:542 -u testuser -t 
messages test
messages=43
[@~]# doveadm mailbox status -u testuser -t messages INBOX/test2
messages=16

[@~]# doveadm -v copy -S 192.168.10.43:542 -u testuser INBOX/test2 
mailbox test
[@~]#

[@~]# doveadm mailbox status -S 192.168.10.43:542 -u testuser -t 
messages test
messages=43
[@~]# doveadm mailbox status -u testuser -t messages INBOX/test2
messages=16 

Also tried with
doveadm -v copy -S 192.168.10.43:542 -u testuser INBOX/test2 user 
testuser mailbox test

Hi,

try running this on the NEW dovecot server:

doveadm backup -u uid -R tcp:192.168.10.43:542

to pull the messages from old server.

This pulls over the whole test mailbox, but I need it to be stored in a 
different mailbox, of course that is now possible to move from the local 
test to the local INBOX/test2. But then I might aswell scp the mbox in 
the first place. 

Should we conclude that it is not possible with a single doveadm command 
to move messages from RemoteServerA/usertest/mailboxA/messagesof2017 to 
LocalServerB/usertest/mailboxX/ ?
