Upgrade to Zivver OWA add-in v4

Introduction

Upgrading from version 3 of the Zivver OWA Add-in is straightforward but not automatic. This document describes the steps necessary for the upgrade:

  1. Locate the current installation of the Zivver OWA Add-in.
  2. Change user assignment.
  3. Install Zivver OWA Add-in v4.
  4. Migrate users from Zivver OWA Add-in v3 to Zivver OWA Add-in v4.
  5. Remove Zivver OWA Add-in v3.

Locate the current installation of the Zivver OWA Add-in

Over the past years Microsoft has moved around the location of the add-in in the admin panel. The location where the Zivver OWA Add-in is installed determines the next steps to update to v4 of the Zivver OWA Add-in. Please check the locations below to see in which of the following locations the add-in is installed:

Change user assignment.

If you’re planning to test the new version with a group of users, please make sure to change the user assignment upfront. If no testing will take place, you can skip this step. Select the Zivver Add-in v3 and edit the user assignment. If the add-in is assigned to ‘Everyone’, change this to the specific group of users who will still work on v3 during the test period. No users should be assigned to both v3 and v4.

Install Zivver OWA Add-in v4

Follow the steps in the Zivver OWA Add-in installation manual to install v4 of the Zivver OWA Add-in. It can take up tot 24 hours before the assigned users see the Add-in as available. See Microsoft’s documentation for more information.

Assign only users who are allowed to test or assign yourself.

Migrate users from Zivver OWA Add-in v3 to OWA Add-in v4

If the tests succeed, you can start migrating users from v3 to v4. To do so, follow these instructions:

  1. Remove the to be migrated user(s) assignment from the Zivver OWA Add-in v3.
  2. Assign the user(s) to the Zivver OWA Add-in v4.
Make sure that at no point a user is assigned to both versions. It can take up to 24 hours before users are assigned Zivver Outlook Web Access Add-in v4. In the meantime, v3 will remain available.

Remove Zivver OWA Add-in v3

When all users have been assigned to v4 and 24 hours have passed, the v3 add-in can safely be removed.
