we are still running Zarafa (Pro/100 users) and would like to migrate very soon to Kopano. We already upgraded our license to Kopano Pro. There are some questions we are not sure about and I hope to get some helpful answers.
OS: GNU/Linux Debian Jessie 64bit
ZCP is connected to our Samba4 ActiveDirectory where all our user accounts are stored. Samba4 Debian package version is called “4.2.14-SerNet-Debian-11.jessie”. The Active Directory schema is extended for the use for Zarafa. With Active Directory snap-in and zarafaads.exe we manage the users on our ActiveDirectory and with the [Zarafa] tab the Zarafa related settings.
We exclusively run Microsoft Outlook as Email client and believe me or not: we already tried everything to bring WebApp to our employees without success. Especially the manager didn’t like WebApp at all, he expressed the necessity of using Outlook as a Groupware client. As a result there are only three employees using also Zarafa-Webapp, all others run Microsoft Outlook on their Microsoft Windows 10 or Windows 7 clients.
Some of our users run Outlook2010 and the others Outlook2013, all of them 32-bit. We have to stick with our current available Microsoft Office products, there is no budget and plan yet to upgrade to Office2016. Most of the employees have attached shared user mailboxes of their colleagues or are accessing shared calendars.
- Outlook 2013 (15.0.4989.1000) 32-bit
- Outlook 2013 (15.0.4911.1002) 32-bit
- Outlook 2010 (14.0.7190.5000) 32-bit
All employees have Zarafa Client version 188.8.131.52189 installed so they can use Outlook.
I am carefully reading through these documentation:
My sorrows and thus questions I have are following:
(1) what happens with the Windows10 client running MS Outlook and the mentioned Zarafa client ? The documentation says:
Note: not all versions of the Zarafa MAPI Outlook client is compatible with Kopano Core. Make sure all clients are upgraded to the latest version before migrating your Zarafa server to Kopano
Will our Windows 7 / Windows 10 clients with Outlook 2010 / Outlook 2013 be able to connect to Kopano server without interaction after I finished the migration process ZarafaServer–>KopanoServer ??
(2) Access to shared accounts and/or calendars are very important. Will the employees be cabaple using this feauture after the migration Zarafa–>Kopano without interaction on their Windows computer? Or do I have to install additionally on each Windows PC the file “KopanoOLExtension-1.6-282-combined.exe” in order to get this feature working ? If KOL is a must-have for Outlook users, is it wise to pre-install it on each of our Windows clients, even before we start the migration process Zarafa–>Kopano ? Will a installed KOL product interfere with our current Zarafa server + MS Outlook setup somehow ?
(3) As I understood Kopano Outlook Extension is only for Outlook 2013 or newer, right? So what happens with our Outlook 2010 clients? Will they be able to connect to Kopano Server with their existing Zarafa client version 184.108.40.206189 but they won’t be able to access shared mailboxes through Outlook because they will miss Kopano Outlook Extension? Does that mean that those employees running Outlook 2010 without Kopano Outlook Extension won’t see the Global adress book anymore ?
(4) What about z-Push? Currently we are on z-push 2.2.10 with PHP-MAPI 7.2.4-29. Is it advisable to download latest z-push version 2.3.9 from http://z-push.org/download/ and install it even now in our actual Zarafa server (before we start migration to Kopano) ? do we have to expect any issues when upgrading to this latest z-push version by still continue using Zarafa server as we actually do ?
(5) Is there anything important I need to be aware of and take special care related to Active Directory bind out Zarafa server is using?
Thanks to anyone for any helpful reply in advance.
