[Sticky] Migration Process of Carbonio Community Edition

If you are going to try script based migration method, you may want to check these threads from this forum related to zmmailbox:

https://community.zextras.com/forum/postid/3712/

So basically, you need to use -t 0 & set socket_so_timeout to a higher value (3000000) for both getRestUrl ( export ) and postRestUrl ( import ) commands.

I'll like to add my 2 cents =)

I made this handful software called Z2C.

Z2C is a quite simple pair of scripts to export LDAP data from an origin Zimbra or Carbonio server and import it on a brand new Zimbra or Carbonio server. It's goal is to migrate accounts and help to dump and restore mailboxes from one server to another.

You can download it here: Z2C

Zimbra to Carbonio - Z2C

I have not started it, but; I appreciate your time and your generosity in sharing it, in advance.

I will complement my experiences

Hello all,

Take a look at these articles as well. You might find them useful: https://community.zextras.com/category/zextras-carbonio/carbonio-admin-guide/migration/

@anahuac I have been blocked while visiting your Site, no way to see anything.

@dominix I have done nothing to block you actively... it's behind CloudFlare and maybe you got caught for some rule of theirs.

You may try to change your IP address or use some public proxy?

Hello!

Is there any successful migration cases so far?

@arukashi yes =)

I migrated my server with quite a few customers in it from Zimbra to Carbonio two weeks ago.

That's why I shared Z2C above to help others to make it easier.

Hi all,

I am planning to migrate from Zimbra OSE to Zextras CE. There is a great migration guide already published but it doesn't cover Active Directory integrated domains. If the Zimbra domains are AD integrated for authentication, how does the migration process change?

Best regards

I did successful migration guided by this article https://community.zextras.com/how-to-use-imapsync-to-migrate-zimbra-to-carbonio-carbonio-ce/

What i didn't understand is why is this part so important:

Important note:
During the installation of new Carbonio CE server, use carbonio.local as a default domain hence the structure of hostname will be mail.carbonio.local and /etc/hosts will be:
ip_address mail.carbonio.local mail
This is the key requirement of this migration method.

I want my destination server hostname same as source, and i can't see why this will break something.

am i missing something?

Thanks in advance

Hello,

I answer my own question. AD integrated domain doesn't change much of the process.

1. First setup external AD authentication then

2. setup autoprovision to import accounts from AD then

3. migrate mailboxes (imapsync or mailbox export/import)

Hi. This article fully covers it - https://community.zextras.com/how-to-use-imapsync-to-migrate-zimbra-to-carbonio-carbonio-ce/

root@mail:/opt/zimbra/backup# /opt/zimbra/common/sbin/slapcat -F /opt/zimbra/data/ldap/config -b "" -H ldap:///???(&(!(entryDN:dnSubTreeMatch:=cn=zimbra))) > /opt/zimbra/backup/provisioning.ldif

This command make full backup of domain and contacts. After restoring /opt/zimbra/backup/provisioning.ldif at new server you will get same AD intergrated domains and its accounts.
