Now I am trying a simpler migration, no multiserver setups. SOURCE is ISPConfig 18.104.22.168, Debian version 6. TARGET is ISPConfig 3.1.3, Debian 8.8. I got dry run to go OK. The migration run seems to fail. I can not see sites generated on the TARGET, and TARGET jobqueue is empty. The generated commands file also fails to copy over anything. I tried the first rsync command, it fails even when I try to cut and paste it to root command line. Code: [email protected]:~# rsync -av --modify-window 10 --delete-before --progress -e "ssh -p22" [email protected]:/var/vmail/kotiZZZZZ.fi/all/Maildir/ /var/vmail/kotiZZZZZ.fi/all/Maildir/ receiving file list ... 28 files to consider rsync: mkdir "/var/vmail/kotiZZZZZ.fi/all/Maildir" failed: No such file or directory (2) rsync error: error in file IO (code 11) at main.c(674) [Receiver=3.1.1] [email protected]:~# I can ssh as root without password from TARGET to SOURCE. The files do exist on SOURCE. On target /var/vmail does exists, but only has mailfilters directory. I can not understand why the rsync command fails. If I try to rsync that same directory with just rsync -av it does work.
