In Place UpgradesHat Tip: Scott Stubberfield, MSFT (@stubbeee)

In-Place UpgradeWhat is it?• Upgrade from Lync Server 2013 to Skype for Business Server using existing

hardware

Benefits• Preserves existing hardware/server investments• Smoother upgrade process without extensive planning• Reduces the overall cost for deployment• The goal of heading towards Smart Setup

Allows Skype for Business updates to be installed as part of Skype for Business Server setup process from Microsoft updatessetup will include an option:

• Check with Microsoft update for Skype for Business updates• Download the updates• Install them (prior to finishing the installation process)

Smart setup

Note: This doesn’t replace the Skype For Business Server update installer—that will still be useful for our customers who don’t have connection to access the internet

Upgrade Paths • Move users to another pool (Minimal User

Downtime)• Offline Mode

Original Topology New Topology In-Place Upgrade Supported ?

2013 Skype For Business Server

+ 2013

Yes. In-Place upgrade support from 2013 -> Skype For Business Server

2010 Skype For Business Server

+ 2010

No. Upgrade from 2010 -> Skype For Business Server is the same process as 2010 -> 2013

2013 + 2010 Skype For Business Server

+ 2013

Mandatory migration from 2010 -> 2013 before deploying Skype For Business Server

Then In-Place upgrade from 2013 to Skype For Business Server

• Migrate-users mode (no user downtime, PoolA. then PoolB)

• Offline mode (take pool down and upgrade)

Upgrade path

Upgrade PathRecommendations• No In-Place Upgrade with Disaster Recovery (Pool-Failover)• Don’t use the Invoke-CsPoolFailover cmdlets to failover the pool!• Don’t start services in Mixed Mode (half upgraded pool)• Don’t Un-Pair the Pools before Upgrade • Ensure minimal time when the Pools are paired with different versions• No Tri-Existence

Upgrade Order(Inside->Outside)User Pools first, then Shared components like:

Mediation Server, Director, Edge, CMS Pool

SQL Support with Lync / Skype For Business Server

In-Place UpgradeSeamlessly Upgrades SQL Express 2012 to SQL Express 2014Also upgrades all the local copies of the database

Step 1: Install Prerequisites

Step 2: Upgrade, publish topology and upgrade databases using Topology Builder

Step 3: Stop the services on all the servers in the pool to be upgraded

Step 4: Run Setup.exe which will launch In-Place Upgrade UI

Step 5: Start services on all the servers in the upgraded pool at the same-time (Use the Start-CsPool cmdlet)

Upgrade Process – 5 Steps!

Step 1 – Install PrerequisitesAlways Install Prerequisites! Install CU5+ latest hotfix to Lync 2013 TopologyPowerShell RTM version (6.2.9200.0) or laterHave at least SQL Server 2012 SP1 installed

You will also need one of the following:Kb2533623 - Windows Server 2008 R2 Kb2858668 - Windows Server 2012 KB2982006 – Windows Server 2012 R2

Step 2 – Upgrade, Publish Top, Upgrade DBs• Move users off the Pool you want to upgrade

• Don’t do a pool failover, just a regular move• Pool pairing can remain intact, but you should spend “minimal

time” in a Lync 2013/SfB Pairing• Don’t do the pool with CMS on first, needs to replicate during

upgrade process• You need a non 2013 Server to install the SfB Management Tools on• Download Topology, Publish Topology to update Topology and DBs• No AD Schema Change (Minor “forest prep” group change, Adding

RTCComponentUniversalServices Group to RTCUniversalReadOnlyAdmins)

• Wait for Topology Update to replicate around all pools, especially upgrade target pool

Publish

Step 3 – Stop the Target FE servicesDisable-CsComputer –ScorchStops and Disables Lync Services

Step 4 – Run setup on Serverssetup.exe /inplaceupgradeLync bits are removed and SfB Bits are installed

Install Process

Step 5 – Start SfB PoolStart-CsPool

Call Quality Dashboard (CQD)Hat Tip: Aaron Steele, MSFT (@skypesamurai)

• QoE Metrics

• LCS CDR

• SSRS – Canned Reports

• SQL Queries (Call Quality Methodology)

• Key Health Indicators

Monitoring Reports

• Rate My Call• Schema changes• Coexistence with 2013, 2013 CU5+ can write

into a SfB Mon DB• Call Quality Dashboard

Monitoring Database Upgrade/Coexistence When you upgrade a Lync 2013 pool to Skype

for Business the associated monitoring database can be upgraded

Excising data is preserved If you start with a new Skype for Business

pool you have to create a new monitoring database No migration of QoE or CDR data from Lync to Skype for Business

• Call Quality Dashboard• Web portal for quickly creating and organizing reports based on

Quality of Experience (QoE) data• CQD deploys a SSAS cube to aggregate the data in the QoEMetrics

database.

• The portal is optimized for several workflows involving QoE data• caching of report data for fast access• deep links to report pages for information sharing and

publishing• streamlined report editing and creation• and editable metadata for report descriptions

• CQD exposes web APIs that give users programmatic access to the cube data for use in custom dashboards

Call Quality Dashboard (CQD)

• QoE Archive• Cube-based reports based on SQL Server analysis

server• Web API access to cube data• HTML5 + JavaScript report portal• Report editing and design• <1s query return performance against SSAS• Support for Lync 2013 and Skype for Business

Local call

Far-end call

1. User instantiates call from Skype for Business rich client

2. Skype for Business client places call to user’s PBX station set (or to any other PSTN phone number)

3. PBX routes call and local user answers

4. When Skype for Business client sees this call answered, places far-end call. Here Skype for Business will use PBX user’s DID as ANI

5. PBX routes call out to PSTN with user’s DID (or to any other local PBX endpoint)

6. Far-end call answers and call is established, with  Skype for Business acting as control channel

Video Interoperability Server (VIS)DeploymentDemo

Skype for Business Room SystemsIntroducing RT100Demo

Agenda

Video Interop Server (VIS)Acts as an intermediary between Skype for Business Server and video teleconferencing systemsHat Tip: Jeff Schertz, Polycom (@jdscher)

What is a VTC?Video Teleconferencing (VTC)Traditional meeting room video conferencing systems

Often deployed with two monitors: one for video and another for content sharing

Can range from small fixed cameras and table microphones to multiple arrays of each

Support variety of standards-based protocols like SIP, H.323, ISDN, TIP…

Some may even support native registration directly to Lync/SfB, but most do not

Lync Room System is not categorized as a VTC

H.264 AVC CompatibilitySo why do we still need more stuff?

Session Initiation ProtocolSession Initiation Protocol Extensions [MS-SIP]

Supported: ms-dialog-route-set-updateSupported: ms-safe-transferSupported: ms-senderSupported: ms-conf-inviteMs-Conversation-ID:ms-keep-alive: UAC;hop-hop=yesms-subnet: 192.168.100.0

Real-time Transport ProtocolRTP Payload Format for H.264 Video Streams Extensions [MS-H264PF]

The Lync 2013 X-H264UC encoder will format the media stream using Network Abstraction Layer (NAL) units such that a standard H.264 AVC decoder can identify the AVC packets apart from SVC packets and then discard any unsupported SVC data.

Real-time Transport Control Protocol

RTCP packets should be sent on every RTP session. Failure to do so can result in loss of functionality and possibly termination of the session by time-out.

What can VIS provide?Peer CallsA VTC user can call a Skype for Business 2015 or Lync 2013 client directlySingle video stream of a specific resolution and frame rate provided by each end

Conference CallsA VTC user can join meetings hosted on a Skype for Business 2015 or Lync 2013 AVMCUCall and conference control actions

What does VIS not provide?No PresenceThe VTC is not registered to SfB Server and VIS does not relay presence information in either direction

No Content SharingNo desktop, application or any other content sharing modality is supported through VIS

No Federated MeetingsA VTC can only join Skype Meetings hosted in the same topology as the trunked VIS pool

No External VTCsOnly VTCs with local network access to the video gateway and VIS are supportedExternal SfB and Lync clients are supported via the Edge Server

What does VIS not provide?No RTV or CCCP SupportVIS only supports transcoding H.264 video for Lync/SfB clientsNo interop with Lync 2010 and older clientsCannot drag-and-drop VTCs into Skype Meetings

No PSTN CallingA VTC can neither place nor receive calls to the PSTN

Limited Standards-Based Features and CompatibilityNo H.323, H.263, ISDN, TIP/ITP (multiscreen immersive rooms)Active Speaker only, no continuous presence or ‘gallery’ view

How does VIS work?A voice trunk, yet for video (and audio)The Video Interop Server acts very much like a Mediation Server

How does VIS work?Transcodes video in both directionsHandles conversion of SVC and AVC streams without the need for traditional transcodingUsed in Peer to Peer Calls and simple Skype Meetings

H.264 SVCH.264 AVC

How does VIS work?Can transcode additional video streamsTranscodes a single AVC stream into one or more SVC streams in conference callsCapability can be disabled to increase scale
