First Steps with the Zimbra NG Modules


This guides contains all information needed in order to switch to the new Zimbra Network NG modules from their legacy counterparts after upgrading to Zimbra 8.8.

It's strongly suggested to take a look ad the specific introductory guide of each module before switching, to learn and understand the differences between each NG module and its Legacy counterpart:


Switching to Backup NG

Switching to the new Backup NG is a simple process that will initialize the new backup system on a dedicated path. Until the initialization is completed, the old backup engine will be active. Old backup files will not be removed and the old backup and restore tools are still available via the usual CLI commands.

Backup Path Limitations

In order to hold Backup NG data, a storage must comply to the following:

  • The storage must have a mountpoint on the system.
  • The "zimbra" user must of course have r/w permission on the path.
  • The data must be stored on a case-sensitive filesystem.

Other than this, there are no hard limitations.

Backup NG Initialization

Before initializing the Backup NG module, make sure you have enough space on the storage you wish to store the backup in. The average size of the backup is 50-70% of the nominal total quota of all mailboxes.

To initialize the Backup NG module:

  • Access the Zimbra Administration Console.
  • Enter the "Network Modules NG" section on the left menu.
  • Enter the "Backup" section.
  • Set the "Backup Path" to whatever directory you wish to store your backup into.
  • Click on the "Initialize" button

Usage Guide

A complete user guide for the Backup NG Module is available in the "Backup Next Generation (NG)" section of the Zimbra Administrator's Guide for your Zimbra version.


Switching to Mobile NG

Switching to the new Mobile NG is a simple process that will activate the new mobile handlers, deactivate the old ones and switch the synchronization control over to Mobile NG from the legacy Zimbra Mobile. Until the initialization is completed, the old mobile engine will be active.

What happens after the switch

After switching to Mobile NG, all existing syncstates will be invalidated, and all connected devices will automatically re-synchronize all of their data through the new engine. The switch is completely transparent to end users, and no user interaction will be prompted or required.

Since the switch will force all connected devices to re-synchonize all of their data, make sure to alert your users beforehand to make sure that they have wifi coverage or enough traffic on their mobile data plans.

Mobile NG Initialization

To initialize the Mobile NG module:

  • Access the Zimbra Administration Console.
  • Enter the "Network Modules NG" section on the left menu.
  • Enter the "Mobile" section.
  • Click on the "Activate" button.

Usage Guide

A complete user guide for the Mobile NG Module is available in the "Mobile NG" section of the Zimbra Administrator's Guide for your Zimbra version.


Switching to HSM NG

The HSM NG module will become active as soon as the upgrade to Zimbra 8.8 is completed, and does not require any interaction.

Any old HSM policy, volume and volume configuration will be maintained.

Usage Guide

A complete user guide for the HSM NG Module is available in the "HSM NG" section of the Zimbra Administrator's Guide for your Zimbra version.


Switching to Admin NG

Switching to the new Admin NG module is a simple process that will migrate any relevant ACL information to the module’s own configuration manager, clearing existing ACLs and ACEs from the system.

The Admin NG module is significantly different than the old Delegated Administration engine. Please make sure to read the product’s documentation and to only migrate to Admin NG if its feature set meets your needs.

Admin Migration is a ONE WAY ONLY process

Admin Migration is a one way only process. Once Admin NG is initialized it’s not possible to go back to the old engine, so if you have customized or complex ACLs/ACEs consider whether switching or not carefully.

Admin NG Initialization

To initialize the Admin NG module on Zimbra 8.7.6 to 8.8.3:

  • Access the Zimbra Administration Console.
  • Enter the "Network Modules NG" section on the left menu.
  • Enter the "Admin" section.
  • Click on the "Migrate" button.

To initialize the Admin NG module on Zimbra 8.8.4 and higher:

  • TBA

Usage Guide

A complete user guide for the Admin NG Module is available in the "Admin NG" section of the Zimbra Administrator's Guide for your Zimbra version.
