14. Lync Hybrid
• What is Lync Hybrid (aka shared SIP domain)?
– A deployment in which some Lync users are homed on-premises
and some are homed within Lync Online, but all users share the
same SIP domain
– Pure hybrid scenario offered as a new feature with Lync 2013 back
end within Lync Online
• Originally, Lync 2010 offered split domain hybrid where users homed in Lync
Online were required to have a separate SIP domain
• What about Lync Hybrid Voice?
– Deployment scenario that allowed users homed within Lync Online
to use on-premises Lync infrastructure for voice calling to/from the
PSTN
• Officially deprecated as of May 2013

15. Lync Hybrid
• What infrastructure is necessary to support Lync Hybrid?
– Lync On-prem
• Lync 2010 Edge server(s) w/ Lync 2010 pool(s)
• Lync 2013 Edge server(s) w/ Lync 2013 pool(s)
• Reverse Proxies
• Optional:
– SQL Servers
– Hardware Load Balancers
– Office Web Apps (optional)
– Group/Persistent Chat servers (optional)

17. Lync Hybrid
• Management Best Practices and Limitations
– Online users managed through Lync Online web GUI and Lync
Online PowerShell
• Lync Online web interface limited in overall management scope
• Accounts must be created within on-premises Active Directory and
synchronized to Office 365 via DirSync before management is available
– Contact Lists
• Up to 1,000 entries supported within Lync Online
• Up to 200 entries supported for migration from Lync on-premises to Lync
Online
– Migration of contacts completed alphabetically from A-Z

18. Lync Hybrid
• Management Best Practices and Limitations
– Policies
• Configurable but not customizable
• Presence policies
– “Maximum followers reached”
– Lync Online presence policy setting might be too low for some customers
• Conference policies
– Hundreds of different policies separated by geographic region, Office365
license tier level, and feature enablement
• External access policies equivalent to on-premises policy availability
• Client policies
– Pre-created policies available, but very limited in scope
– No control over pictures, emoticons, customized Enterprise Help URL, etc.
– Dial-In Conferencing
• Supported within Lync Online through a qualified audio conferencing provider

19. Voice, Conferencing & ACP Considerations
• Do you need to integrate with your existing PBX (Cisco, Avaya, etc.)?
– Yes  Lync on-prem or possibly a combination of Lync Hybrid
• Do you want to replace your existing PBX (Cisco, Avaya, etc.)?
– Yes  Lync on-prem or possibly a combination of Lync Hybrid
• Do you want to reduce your yearly spend on outsourced dial-in
conferencing?
– Yes  Lync on-prem or possibly a combination of Lync Hybrid
– Remember with Lync Online, there is still a yearly outsourced ACP
integration expense
– What is the concurrent call volume and circuit utilization today compared to
expected levels?
– Do you have PRIs and/or SIP trunks?
– Understand ingress/egress points compared to user locations

20. Voice, Conferencing & ACP Considerations
• Are you worried about the bandwidth necessary to support on-prem dial-
in conferencing?
– If Lync on-prem is selected, new third-party software has been developed
by ACPs that can integrate into Lync on-prem and pump the audio stream
into the Lync MCU via federation (instead of PRIs or SIP trunks)
– Intercall ECC Lync Edition or Level 3 (soon)
• Do you have a global/regional footprint and are looking to use Lync
Online for all dial-in audio conferencing?
– Review your Office 365 tenant location and the ACP (Intercall, PGi, or BT)
conferencing hub integration points
– For example, if Office 365 tenant is located in NA, it’s possible all ACP
traffic must originate from the tenant’s regional hub

21. Customer Migration Scenario 1
Scenario:
– Customer has OCS 2007 R2 deployed and is looking to move to
Lync Online
Requirement:
– Customer would like to retain contacts from OCS 2007 R2 to Lync
Online
– Customer uses OCS 2007 R2 for IM/presence and federation, but
does not use Live Meeting conferencing functionality

22. Customer Migration Scenario 1
Recommendation:
1. Deploy Lync 2013 on-prem, ADFS, and DirSync
a. Recommended way to migrate contacts from OCS 2007 R2 on-prem to Lync
Online
2. Deploy specific Lync 2013 on-prem DNS records
3. Develop communication, training, and software deployment strategy
4. Migrate users from OCS 2007 R2 to Lync 2013 on-prem
5. Upgrade Communicator clients to Lync 2010/2013
6. Enable Lync Hybrid mode
7. Grant Lync Online (Plan 2) rights and policies in Lync Online Admin
portal/PowerShell
8. Migrate users from Lync 2013 on-prem to Lync Online
9. Disable Lync Hybrid mode
10. Decommission Lync 2013 on-prem servers
a. ADFS & DirSync will remain for Lync Online and other services (Azure,
Exchange Online, SharePoint Online)

23. Customer Migration Scenario 2
Scenario:
– Customer has OCS 2007 R2 deployed and is looking to move to
Lync Online
Requirement:
– Customer will not be migrating contacts from OCS 2007 R2 to Lync
Online
– Customer uses OCS 2007 R2 for IM/presence, federation, Live
Meeting, and Dial-In auto conferencing functionality

24. Customer Migration Scenario 2
Recommendation:
1. Deploy ADFS and DirSync
2. Deploy specific Lync Online DNS records
3. Develop communication, training, and software deployment strategy
4. Provision ACP contracts and conferencing info
5. Grant Lync Online (Plan 2) rights and policies in the Lync Online Admin
portal/PowerShell
