Microsoft Supported Method to Move from Pure Lync Online to #Lync Server On-Premises/hybrid deployment

07/05/2014 11 Comments

This is a scenario we are hitting more and  more, and are working with a number of customers on right now. Microsoft are increasingly offering Office 365 licencing, which means customers who haven’t previously had Lync can quickly enable Lync Online for basic IM/P and a bit of voice and video (there is still no PSTN/Enterprise Voice in Office 365).

Customers get to X seats in Lync Online, then decide they want to deploy Lync Server on-premises, reasons include:

  • Enterprise Voice (True PSTN numbers, Response Groups etc.)
  • Network/QoS/Bandwidth/CAC Reasons
  • Compliance
  • Server Side Application Development/3rd Party Application Integration
  • A certain country/region/office/department cannot be “in the cloud”
  • Customer has bought E4 licences, giving them user rights for Enterprise voice On-Premise

Until now, unfortunately, there has been no clean way to do this. The official Microsoft guidance was to disable the Lync Online deployment (disabling all the users) then deploy Lync Server, then re-enable Lync Online/hybrid, then re-enable the Online and On-prem users. This wasn’t very practical both in terms of downtime and there was no easy way to export users buddy lists (other than exporting them one by one with the users password). There were hacky ways around this, but nothing supported. The other option was to have a different SIP domain on-prem, again, this was messy.

Now there is an officially supported process to move from pure Lync Online to on-premise/hybrid:  Moving users from Lync Online to Lync on-premises

Note Scheduled meetings for Online users are not migrated and need to be recreated, but users can be moved with their complete buddy list.

I have yet to test the final documented process, but have a number of projects coming up involving this and will report back on the blog, sign up for RSS/email updates. If you have feedback please let me know.

    Microsoft have made this so confusing. So you are saying it is possible to have a Hybrid Lync deployment between Lync Cloud and On-Premises using the same domain ? Is there any documentation out there on how to achieve this ?

    Also, would the Lync Cloud be able to support conferencing ? Or dial-in conferencing through the On-Premises Lync server ?

    • Hey Hany,

      Nothing about having a hybrid/split domain setup changes; yes you can have the same domain in the cloud and on-prem, anything PSTN/Dialin conf would be on-prem typically.

    Hi Tom – I actually worked jointly with a customer and Microsoft Lync Product Group to validate the beta process for the procedure that formed the basis for this article.

    My customer had 1000 users lit up for Lync Online and we successfully enabled the Lync On Premise deployment to “see” the Lync Online users. We were then able to move the users from Online to On Premise without losing buddy lists. Scheduled Meetings were lost however (we knew this going into it) and needed to be recreated as you point out. I have to say the final procedure is slightly different than what we followed so it appears some further revisions were made to simplify the process. I will need to run a test to confirm all still works as expected.

    Once you run through it the behavior of the Lync On Premise server will behave just like you started with On premise and added Lync Online integration later.

    Hi Tom,

    I am interested in your article and I have some questions, at the moment we are using Office 365 for our users we just want to deploy PSTN connectivity, we don’t have any lync/onprem I know that MS is working with Service provider to give PSTN connectivity but I want to know if I deploy Lync/onprem and connect it to a SIP provider, can I use this server as a VOIP gateway for my Lync Online user, I don’t want to move them, I saw this kind of product :

    Hi Tom , I am just about to travel this road for a customer , have you any updates or gotchas you can share ?

    Thanks Ant

    • Hi Ant.

      I’ve heard of a number of people completing this successfully now, mainly MCS, and a couple of people that hit an odd issue or two with some specific users, where they just decided to delete them and re-create them.

      Main thing to consider is that sign in dependency for all users now relies on the on-prem, which is an important considerations for EV pilots.

      I still haven’t done it first hand.

      thanks

      Tom

    Tom,

    Do you know of any guides or supported methods for moving from Hybrid to pure Lync Online? Once all users are moved to Lync Online, is it just a matter of changing the DNS records for the domains to point to Lync Online only and then decommission the on premises Lync infrastructure? And also tell Lync Online it will no longer be doing split domain?

    • You can have a mix of users online and on-prem. I don’t know of any guide beyond the steps Microsoft have released at the link above. All DNS should ultimately point to Lync On Prem.
