script or command move mail blocks between server zimbra

[juan_cipolletti]

Hi, I'm new to the forum and in the world of zimbra,I would need some script or cli command, to move by blocks of accounts and by date periods, the emails from one server(ver.8.0.6) to another(ver.8.8.15)

best regards,

best regards,

How you do that depends on whether the two servers are in the same LDAP realm or not. If they are in the same Zimbra cluster, then you can use zxsuite hsm domailboxmove (or if OSE zmmboxmove).

If they are totally separate servers, you have a number of options, but you may want to start here: https://wiki.zimbra.com/wiki/Split_Domain

Hope that helps,

Hi Mark, thanks for answering, the scenario is like this, I am conducting tests to later apply it in the production environment. I am migrating the current server with CENTOS 6 + ZIMBRA 8.0.6 to CENTOS 8 + Zimbra 8.8.15, I already made the transfer of accounts, domains, mailbox attributes, etc. I only lack the emails of about 600 boxes. As the volume of accounts and their emails is huge, I want to do it little by little, for the users to connect to the new server and start to see their historical emails little by little ...

Best,

For that scenario, I'd use the IMAPSYNC tool. https://imapsync.lamiral.info

You can cut over everyone at the same time if you wish; just run IMAPSYNC once or twice to prepopulate the mailboxes, change DNS to point to the new server, and then let imapsync do a final "catch up".

Only (big) problem I see is that the new server is running CentOS8, which goes end of life at the end of this year (2021). CentOS7 goes EOL June 30, 2024.

All the best,
Mark

Yep... Had some success with centos2ol.sh script today and it even worked so that might be an option for those that want the 10 years they were promised for RHEL8 or need a pathway via their cloud provider that doesn't support Oracle linux in their KVM's/etc.

Pretty simple to use and didn't require a reboot if you don't install their "Unbreakable Enterprise Kernel"... NO UEK for us. Got to love marketing!

Hi Mark, thanks for answering, I was doing tests with the command "zmmailbox" + "//? fmt = & query = after: before:", but without success (ERROR: service.FAILURE (system failure: GET from http: //zimbra.laboratorio .com.ar / home / xxxxx @ xxx.com.ar /? fmt = tgz & query = after: 01/01/2020% 20before: 01/31/2020 failed, status = 500. Server Error), I tried all variants of quotes, etc,
I am going to try the imapsync command, could you help with some example how to use it for my need?
I'll also take the CentOS8 end-of-life issue


Hi Jdunphy, thanks for answering, I am going to investigate / read the link that you mention and the script that you suggest to migrate from Centos8 to Oracle linux; If you have any tips for your recent immigration experience, I thank you very much

Thank you so much to both

Here is what I did for a few test instances and both worked. CentOS 7 or 8. We are running a current and newish kernel from our Cloud provider so the UEK isn't of interest but they claim to have perfected kernel patches without a reboot which may be required with the default RHEL kernels in some circumstances.

Code: Select all

% su - 
# wget 'https://raw.githubusercontent.com/oracle/centos2ol/main/centos2ol.sh'
# chmod 755 centos2ol.sh
# ./centos2ol.sh -kV

It's a fairly quick and uneventful conversion. I'll continue testing this more as I need to have a back-out strategy for our CentOS with EOL soon.

Thanks Jim for your quick response to the Centos8 end of life "problem", I will start the tests after finishing the migration of Zimbra. Which would be needing some initial help for scripting with imapsync, because I am not an expert in unix / linux shell scripting
