Hi all
I have a client company who have about 25 users using Lync 2010 only for IM and presence functions. There is currently no audio/video, conferencing or any other usage. We need to move them to Lync Online and stop using Lync 2010.
I feel that doing a full migration to Lync Online by setting up an Edge Server and hybrid move (Move-CsUser) would be overkill for the simplistic needs we have here. Therefore, I have made the below plan.
1. Set up DNS records correctly for Lync Online as specified in the 'Domains' section in Office 365 admin center.
2. Uninstall Lync 2010 on-premises and remove all internal SRV, CNAME and A records that point to the Lync server or are Lync related.
3. After this, when the Lync clients try to log in using O365 user credentials, I expect them to correctly log in to Lync Online.
Can the more experienced users advise if this plan is good or if you see any issues / missing bits in this? Is there a better way of doing this?
P.S. I understand that this method will not migrate any user data like contact lists etc and they will have to re-add the contacts.
Hope to hear soon and thanks in advance for all help.
Regards
Nauman.
