Migrating from qmail server, invalid option "o" in dsync
Hi folks,
I have an old server running qmail with several years of mails in maildir
format I want to migrate to a new server, without requiring fresh client
download of everything.
Old server is debian 6(?). Local IP is 192.168.0.1.
New server is Debian 10, local IP is 192.168.0.25.
I have dovecot 2.3.4.1 (latest from apt stable) installed and apparently
working - if I manually copy the home directory for my account, I can
connect (using thunderbird) and I get all the emails appearing as new,
forcing redownload. Seems like the new config is at least functional.
I'm trying to follow the migration guide at
https://wiki2.dovecot.org/Migration/Dsync, but I am getting an error
message:
root at newserver:~# doveadm backup -R -u _user_ -o pop3c_user=_user_ -o
pop3c_password=_password_
backup: invalid option -- 'o'
doveadm backup [-u <user>|-A] [-S <socket_path>] [-fPRU] [-l
<secs>] [-r
<rawlog path>] [-m <mailbox>] [-g <mailbox_guid>] [-n
<namespace> | -N] [-x
<exclude>] [-s <state>] [-t <start date>] -d|<dest>
Have tried this a couple different ways and according to everything i can
find -o should be valid. Can anyone tell me what I'm doing wrong here?
Thanks!

With pop3 migration you can't save the imap uid:s and all clients will see the mails as new. Sami -------------- next part -------------- An HTML attachment was scrubbed...
