which imap server uses kopano



  • Hi@all,

    I’m a new kopano admin an I must migrate mail from kolab to kopano. Witch imap-server use kopano in the background and where is it storage mails in fs?

  • kopano-gateway is the IMAP server. Mails are normally stored by kopano-server, usually in MySQL, though may internally get copied to /var/lib/kopano/attachments for faster output to IMAP clients.



  • Hmm, that means I have no option to transfer imap-accounts from kolab to kopano by using a tool like imapsync e.g. ?



  • imapsync should work. In fact, the utility “kopano-migration-imap” is based on it.



  • @jengelh said in which imap server uses kopano:

    kopano-migration-imap

    What is “kopano-migration-imap” and where can I get it?


  • Kopano



  • I have a final question. It is possible to use the tool to migrate the mails (imap) over the lan connection? Example:

    My old mails in kolab on host: kolab.local.lan
    My new kopano ist on host: saturn.local.lan

    I install a new vm (ucs member) host: transfer.local.lan an install the package “kopano-migration-imap” on this host, transfer the mails and kill the vm.

    Hi you don’t need a third machine you may install “kopano-migration-imap” on host: saturn.local.lan and tranfer through lan from kolab.local.lan

  • *The package kopano-migration-imap required some dependencies that are not part of the official Univention repositories, but are available from the “unmaintained” *

    it is possible to remove everything clean from the system when I finished?


  • Kopano

    that would be a more fitting question for the Univention forum.

    OK I will do it. Back to my question before … it is possible to transfer with a third machine? A vm with ucs a member are ready in 15 min and after the migration I send her to nirvana :-)


  • Kopano

    @pixel said in which imap server uses kopano:

    yes, absolutely.



  • ok, vm ist up and running … the save way :-)



  • ok, i set the variable:

    ucr set repository/online/unmaintained=yes
    

    and:

    apt update
    

    but I can find a package:

    root@ucstest:~# apt search kopano
    Sortierung... Fertig
    Volltextsuche... Fertig
    

    or:

    WebUI -> Packache -> search -> kopano

    What’S wrong?



  • ok, I have to install kopano-core on the test environment before I try tu install the migration-tool . My mistake



  • Ok, i try to start the migration from an kolab server with:

    kopano-migration-imap --noauthmd5 --host1 192.168.1.72 --user1 'user1@domain.de' --password1 '#geheim' -sep2 / --prefix2 "" --host2 192.168.1.6 --user2 user1.ganz --password2 '#geheim'
    

    but I become:

    any experience with kolab?


  • Kopano

    Hi @pixel ,

    what you installed is merely a packages imapsync. so you should be able to follow examples given for imapsync, for example https://wiki.kolab.org/Imapsync



  • Ok, it works.For migrate from kolab3 -> kopano:

    -Backup your Kolab3
    -Export Adressbook&Calendar with Kolab-Webmail
    -Delete the Kolab-Groupware-Folder (Calendar, Files, Journal …)

    kopano-migration-imap --host1 [Kolab-IP]--user1 'primary.mail@adress.de' --password1 '#geheim' --ssl1  --authmech1 PLAIN -sep2 / --prefix2 "" --host2 [Kopano-IP] --user2 'user2' --password2 '#geheim'
