Hello Timo,
"old server" is running dovecot 1.0.15, so I guess it it will not
support imapc_features=modseq...
Maybe it would be useful to add these prerequisites to dovecot wiki.
Regards,
Cédric

Hello,
I'm trying to migrate mail accounts from an old server to a new one.
As I need to migrate dozens of accounts which take about 1G each, I need to do
stateful sync to make my migration in two times :
1 - I run a :
doveadm -D -o mail_fsync=never -o imapc_user=us...@olddomain.fr sync -s "" -R -1 -u
us...@newdomain.fr imapc: > /tmp/firstsync.log 2>&1
my accounts are synced, and I get a "state" string (AQAAAHm4+Jk=) as the output
of doveadm sync command.
Stateful synchronization requires at least imapc_features=modseq. That requires
that the remote server supports CONDSTORE IMAP extension. And I'm still not
entirely sure if that's enough. In general stateful replication isn't really
supported with imapc.
