Hello All,
We are having a multiserver infrastructure running on Centos 7 with 8.7.11 p13, we are planning to migrate the current setup on a new infrastructure then upgrade it to the latest version.
Could someone help us to get a proper solution for this process?
The main concern is we need Calendars, tasks as it is configured on the current server to new systems with data.
I have gone through lots of articles related to the upgrade process and read lots of approaches.
Do I need to follow step by step like version to version upgrade after moving current DB, config to new systems till the latest version Or can we directly migrate from 8.7.11 to 8.8.15?
If someone is having the steps, can share would be appreciated.
Regards,
Dany Kallery

Re: ZCS upgrade from 8.7.11 to latest 8.8.15
I just moved from rhel6 to rhel7 and then from 8.7.11 to 8.8.15. I did with just 2 servers as a Swing upgrade because there were network changes as well and our Enterprise does not move quickly unfortunately. This allowed me to have our team test it out before moving everyone else.
The basic steps were:
1. create new servers and install same version of zimbra (I put LDAP replica/mailbox/etc on one and proxy/mta on another)
2. Move loggerhost to new primary mailbox node.
3. Move all the users over the weekend. Watch out that disk doesn't fill up. Something like:
4. Promote LDAP replica to master: https://wiki.zimbra.com/wiki/Promoting_ ... Master_8.0
5. Delete old servers (outdated but OK go-by, I also grep'd entire output of ldap which is how I found distros need moved): https://wiki.zimbra.com/wiki/Removing_A_Mailstore
6. Just run install.sh of new 8.8.15. This took maybe 30min to run on mailbox node.
I found distro lists did not move. I did that manually with ldapmodify. I will have to get this while at work if interested. Also, I would start with the upgrade to 8.8.15 rather than end with it but when I started 8.7.11 was still LTS...

zmprov -l gaa -s oldserver | while read -r user; do zmmailboxmove -s oldserver -t newserver -a "$user"; done

Thank you so much for the tips. Let me prepare a test infra then follow these steps.

I am planning for a proper migrate from Centos 6 to Centos 7 and then
upgrade from 8.7.11 to 8.8.15.
Shall I install new server with centos 7 and 8.7.11 and execute rsync for /opt/zimbra then only upgrade manual for zimbra with the method below?
https://wiki.zimbra.com/wiki/Zimbra_Releases/8.8.15/P14
this method of upgrade is Installing Zimbra packages individually

Re: ZCS upgrade from 8.7.11 to latest 8.8.15
Install a new CentOS 8 server then install the Zextras build of ZCS 9, once you've done that install the ZeXtras package on both servers and then do a server incremental: https://docs.zextras.com/zextras-suite- ... ackup.html
Re: ZCS upgrade from 8.7.11 to latest 8.8.15
Using the zextras suite within 30 days of free trial?
Cause the fee for 500 mailboxes quite a hefty sum.

Yes, there's a thirty day trial that you can use.williaml wrote:Using the zextras suite within 30 days of free trial?
