Why upgrade to Teams?
*The Forrester Study: The Total Economic Impact™ Of Microsoft Teams outlines cost savings
and other financial benefits organizations can realize by adopting Teams
Advanced features, modern experiences
• Teams combines chat, video, calling, collaboration,
and app integration into a single, integrated hub
• State-of-the-art cross-platform and mobile experiences
Performance by design
• Reimagined client built on cloud infrastructure
• Teams provides improvements in call and meeting quality,
and other operational metrics
Bottom-line benefits
• In a recent study, organizations that moved to Teams saw
cost reductions from consolidating solutions to one platform,
had 14.6% less downtime due to online availability of resources,
and projected a three-year net present value per user of $5,416*
Skype for Business Online
retirement
• Skype for Business Online will
be retired July 31, 2021
• Skype for Business Server is not
affected, but customers with hybrid
configurations will need to move
Skype for Business Online users to
Teams by the retirement date

#M365VM
Paths to Teams
• Starting point in all cases includes Skype for Business
• End point is all users using Teams Only
• Driving adoption in your key scenarios in Teams is critical success factor
• Key considerations when deciding your path:
 Feature requirements & overlap between SFB and Teams
 Moving users all at once or in cohorts
 Velocity to move users to Teams Only
Cohort 1 Cohort 2 Cohort 3… All users

18. May 27 & 28, 2020
Vignesh/Vijai | EN
#M365VM
Which coexistence path should customers take?
Microsoft offers flexibility for customers to choose their upgrade path on the road to Teams Only
Teams side-by-side to SFB with Chat, Meetings & Calling
Considerations:
• Skype for Business Online and most on-premises (recommended path)
• Capabilities available in both SFB and Teams
• Enables quick velocity move to Teams
Teams side-by-side to SFB with selected features (Collab, Meetings)
Considerations:
• More complex environment with on premises enterprise voice
• No overlapping capabilities between SFB and Teams
• Designed with longer co-existence period in mind

Side-by-Side with overlapping features
• Introduce Teams side-by-side to Skype for Business with Chat, Meetings
and Calling enabled *
• Drive your adoption program
• Upgrade all users or one cohort at the time to be using Teams only

• Receives chats and calls in same
client as the one used by
originator
• PSTN calls in SfB
• Can initiate calls and chats from

Chat

Meetings
Collaboration

25. May 27 & 28, 2020
Vignesh/Vijai | EN
#M365VM
Considerations & Impact
Moving users
all at once or in
cohorts
 All at once: Ideal option for best user experience
Quick velocity: All users have the same capability and experience at once
which simplifies adoption
 Cohorts: Increased success when users adopted all the key scenarios in
Teams
Slower velocity: Large organizations may move slower, however when
Teams deployed to all users there will not be interop experiences
 Chat messages and calls from federated customers will be received in
Skype for Business until you move to Teams Only
 Phone System capabilities will only be available when users in Teams Only
 HID and meeting room devices
 Chat and calling will be available in both SFB and Teams
 Meeting scheduling and joining is available in both products

#M365VM
Considerations & Impact
Moving users
all at once or in
cohorts
• All at once: best option for small to medium organizations to introduce
new features org wide
Quick velocity: All users have the same capability and experience at once
which reduce the likelihood of interop experiences
• Cohorts: Different group of users will have different experience. Interop is
triggered when the first cohort is fully migrated to Teams only
Slower velocity: Path B is designed with predictability in mind and since
there is no overlap in functionality migration velocity is less crucial
• Phone System capabilities will only be available when users in Teams Only
• Federation follows the user’s reachability for chat and calling
• Chat and calling will be available only in Skype until the user is moved to
full Teams only experience. Predictable experience
• Meeting scheduling will be available in one product only, users can still
join from both products

Direct Routing Architecture for Teams
Requires a Microsoft Certified SBC to allow you to bring your Telco Service provider for dial tone.
Directly Route dial tone to Teams Users
Direct Routing in Office 365 allows customers to connect their SIP trunks
directly from their network. Customers can work with their local
Telecommunications provider to enable Microsoft Teams users to make and
receive telephone calls.
Interoperability with 3rd party systems
Direct Routing allows customers with users in the Microsoft cloud to
continue using 3rd party systems such as PBXs, Call Center, and Analog
Telephony Adaptors (ATA) helping preserve key investments.
