Migrating from qmail server, invalid option "o" in dsync
by Justin Coleman 01 Aug '20

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@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?
