© 2020 Cisco – CTG TME. Collaboration Transitions – Messaging: IM&P / Webex Messenger to Jabber Team Messaging
This scenario applies specifically to transitioning Jabber messaging workload from on-premises Unified CM IM&P to Webex Teams.
Messaging: Transitioning to Jabber Team Messaging ModeScenario Introduction: Decision
Do not make the transition if you have these requirements:» Very strict compliance requirements
• Pre-delivery message blocking• Ethical firewalls• FIPS1 mode
» B2B federation with third-party messaging service» Intradomain federation with Microsoft» Heavy use of Jabber IM only mode desktop share

Messaging transitions scenario covering transition from an on-premises to cloud messaging service
Scenario Objective
• To evaluate the transition FROM traditional on-premises Cisco Unified CM IM & Presence (IM&P)1 TO cloud-based Cisco Webex Teams.
• To explore the messaging solution transition with a focus on:
» User experience: Messaging features and functions.
» Administrative experience: Provisioning, management, and troubleshooting.

» Architecture based on the Enterprise On-Premises Preferred Architecture (version 12.x).
» Messaging deployment with on-premises Unified CM IM&P.
» Directory for corporate identity (Active Directory).
» Jabber clients register to on-premises Unified CM call control.
» Expressway-C/E pairs for firewall traversal: Clients connect to on-premises services directly or optionally through Expressway.

• Messaging resources are moved from on-premises (Unified CM IM&P) to cloud hosted (Cisco Webex Teams Messaging).
• Only features and functions for on-premises1 messaging deployment were evaluated with the Cisco Jabber Team Messaging mode solution. (Phone mode is not part of this scope).» 80/20 Rule: It is expected that this scenario will be applicable to ~80% of customers,
understanding that ~20% of customers may have additional considerations or requirements not covered. However, even in those cases, this transition map may still be used as a potential future transition path.
• Only Cisco Jabber (desktop and mobile) was evaluated.» All clients remain registered to on-premises call control: Unified CM.
» Cisco Webex Teams clients are not considered for this scenario.

• Licensing: Move to Flex Licensing.
• User Accounts: Users must be synchronized with organization’s Webex identity store/added in Webex Control Hub.
• Messaging Resources: Remove on-premises Unified CM IM&P messaging / presence service nodes.1 These are no longer needed with cloud messaging.
» Interoperability (optional): Hybrid Messaging interop can be deployed for Unified CM IM&P to Webex Teams. These capabilities are optional for organizations who will do a phased migration.
• Migration Process: Administrator can enable the migration from Webex Control Hub. Jabber 12.5 or later deployments automatically discover that a migration is required.
• Contact List Migration: User Contact Lists can be migrated on a per user basis.
• Presence: Presence model is based on user activity.

1 Maintain Unified CM IM&P for phased migration or if co-existence (dual messaging services) is required. Consider hybrid messaging interop to address co-existence scenarios.

• Jabber Team Messaging mode allows an organization to move their messaging workload from on-premises to the cloud-based Cisco Webex Teams platform.
• Delivers the same recognizable Jabber user experience making the transition seamless for existing end users.
• Maintains the same Unified CM calling feature set with no loss of calling functionality.
• Fully supported with VDI deployments of Jabber.• Meeting workload remains the same whether hosted on-premises (for
example, Cisco Meeting Server) or in the cloud (for example, Cisco Webex Meetings).

There are many other compelling reasons for transitioning from on-premises to Cisco Webex cloud messaging:
• Persistent messaging with file sharing: 1:1 and Spaces
• Reduced total cost of ownership (TCO)
» No requirement for on-premises Unified CM IM&P services nodes.
» No need for external database / file servers for persistent chat.
• Webex Teams messaging APIs for highly accessible integrations
• Instant global federation with other Webex Teams organizations

The following tables highlight key technical considerations to be aware of when transitioning from the on-premises messaging deployment toa cloud-based messaging deployment.The considerations have been divided into the following categories:
» Compliance» B2B Federation» Presence Model» Desktop Share» Contact List
Messaging: Transitioning to Jabber Team Messaging ModeWhat is Different When Moving to Jabber Team Messaging?
21
© 2020 Cisco – CTG TME. Collaboration Transitions – Messaging: IM&P / Webex Messenger to Jabber Team Messaging
Category Considerations
Compliance
• The Webex Teams platform does support integration with third-party compliance engines.• Message blocking is implemented after message delivery.• Ethical firewalls are not currently supported in Jabber team messaging mode.• FIPS mode is not currently supported in Jabber team messaging mode.
Considerations for compliance
Messaging: Transitioning to Jabber Team Messaging ModeCompliance Considerations
22
© 2020 Cisco – CTG TME. Collaboration Transitions – Messaging: IM&P / Webex Messenger to Jabber Team Messaging
Category Considerations
B2B Federation
• The Webex Teams platform supports messaging federation with other Webex Teams orgs (this can be disabled).
• Webex Teams does not support native B2B federation with other vendors (XMPP or SIP). NOTE: services such as m.io can provide interop to Microsoft Teams or Slack.
• Intra domain federation to Microsoft Lync is not supported.
Presence Model
• Webex Teams implements an activity-based presence model: Active, Active 10 mins ago, On a Call, Inactive, and so on. Activity status is based on using the application.
• Unified CM IM&P implements an Availability based presence model: Available, Away, On a Call, and so on. Availability status is based on user setting/being logged into your device.
• Unified CM IM&P also supports custom presence statuses, including user set location information.
Considerations for B2B federation and presence model

Considerations for desktop sharing and contact lists
Messaging: Transitioning to Jabber Team Messaging ModeDesktop Sharing and Contact Lists Considerations
24
Category Considerations
Desktop Sharing
• Jabber with Unified CM IM&P and Jabber team messaging mode, both support desktop sharing when on a call.
• Jabber for Windows with Unified CM IM&P supports desktop sharing from a messaging only session. This desktop sharing also supports remote control. This functionality is not supported in Jabber team messaging mode.
Contact Lists
• Jabber team messaging mode supports contact lists. Contact lists can be maintained when migrating from Unified CM IM&P to team messaging mode.
• Contact lists cannot be managed via Enterprise Groups.• Contact lists cannot be managed in bulk (administratively).
