Hello,
We have been using some Community scripts to manage Zimbra Backup & Restore. With over a thousand users, I want a much better solution. After conversations with others I've downloaded ZExtras for a trial, and if it works like I believe it will, it will be my choice going forward.
We are upgrading the Zimbra7 production server to new hardware; At the same time we will upgrade to Zimbra8. When its done I will turn off the Z7 server using only the Z8 server in the future.
As I understand, I can use ZExtras Backup to execute a migration between a Z7 & Z8 server with very little downtime, using an Incremental Migration process.
I've read Forums posts and the online documentation. I understand the general process for migrations, but everything I read still misses clear details for configuring the Destination server.
I see many people have some similar questions. I hope to get a "once & for all" answer that is useful for everybody!
My current situation is:
Z7 runs on Ubuntu10.
ZExtras Suite Core & Zimlet are installed
there is NO nameserver running on the Z7 server; there IS a nameserver on the same LAN.
the Z7 server's hostname ~= "zimbra.domain.com".
the Z7 server's IP = 192.168.1.42
the Z7 server's main domain is "zimbra.domain.com"
the Z7 server's SSL cert is for "zimbra.domain.com"
Forward & Reverse DNS is configured so
dig A zimbra.domain.com +short
192.168.1.42
host 192.168.1.42
42.1.168.192.in-addr.arpa domain name pointer zimbra.domain.com.
And the /etc/hosts on it is
127.0.0.1 localhost.localdomain localhost
192.168.1.42 zimbra.domain.com zimbra
::1 localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
It works this way very well and with no problems.
I will set up the new Z8 server on Ubuntu 12 on a machine that is on the same LAN.
The IP address & hostname of the Z8 server must in the end be the same as the Z7 original server.
But we cannot have these the same during the Z8 installation and the Z7->Z8 Incremental migration.
My detail questions are, to make the Zextras Incremental Migration work without problem,
(1) When I 1st setup the machine for the Z8 server, what must be
its FQDN hostname?
its IP address?
the DNS results for its hostname & IP?
the contents of its /etc/hosts?
(2) When I install Z8 on the Z8 server machine, what must be
the main domain I assign to Z8?
In the end I am looking for the Step By Step sort of Guide for this specific procedure!
