Zimbra Next Generation Modules/Things To Know Before Upgrading
Upgrading from version between 8.0 to 8.6
Upgrading to 8.8 is supported but there are a number of items you need to be aware of:
- 8.8 requires the installation of the proxy server on all setups. In most cases a single server installation does not have proxy installed and configured. The following command can be used to see if proxy is installed and enable.
[zimbra@Server ~]$ zmprov gs `zmhostname` |grep zimbraService |grep proxy zimbraServiceEnabled: proxy zimbraServiceInstalled: proxy
If proxy shows as installed and enabled then proxy is running within your system. If not, then you will need to enable proxy by following the Enabling Zimbra Proxy and memcached wiki.
Upgrading from version between 6.0.8 to 7.2.x
In most cases, Zimbra Support recommends doing a migration to a new system, for more information, please see Incremental Migration using Next Generation Backup
There are no new license requirements for next generation modules. All new modules require a valid license and the number of accounts that can use the Mobile modules will be limited to the number defined by MobileSyncAccountsLimit within the license. You can verify the license by running the following from the command line:
During the upgrade process you will be prompted to install the new Modules
Install zimbra-chat [Y] Install zimbra-drive [Y] Install zimbra-imapd [Y] Install zimbra-network-modules-ng [Y]
IMAPD is a beta feature but the installer is set to install the packages as part of the default installation. Because the module is independent from the remaining modules and needs to be enabled after installation, this will not effect to your current production installation. If you like to exclude the module from your installation, you can enter N when selecting modules section of the installation process.
Install zimbra-imapd [Y] N
Because IMAPD is a beta module, it is not a supported feature and is recommended only to be enabled on non production systems.
