<-- Prepare Hybrid environment for Microsoft Teams or Skype for Business online - Part 2

When planning the hybrid solution for Skype for business or Lync with Skype for Business Online or Teams, it is important to consider how end client or endpoints such as phones, conferencing phones and meeting room video system compatible with the solution.

Skype for Business client

Even though the on-prem system is Lync 2013 many of the users use Skype for Business client. It would be a very rare situation that finds any use uses Lync client. Therefore, I mainly discuss here SfB client.

There are some differences when running SfB clients on on-premise servers’ vs SfB hybrid and SfB Online services. The below considerations must be made when planning to either deploy hybrid or cloud-only SfB users. Considerable planning must be made, and communication must be clear to ensure stakeholders and users.
  • Users can only have up to 250 contacts in Skype for Business Online. This limit will be honoured when migrating users from on-premises
  • Conferencing data & meeting content meetings are not migrated to SfB Online.
  • Only cloud policies will be applied to the users, so policy settings must be captured and recreated on-line.
  • Users enabled for Lync 2013 Enterprise Voice in on premises must have a Phone System license assigned in Office 365 before they migration. Concerning Conferencing Data & Scheduled Meetings

Must ensure that the Meeting Migration Service (MMS) has been enabled within the Office 365 tenancy (I have discussed it on my previous post). The service is responsible for migrating any future meetings as part of the hybrid migration session.
By default, MMS is automatically triggered during each user’s hybrid migration window.

On-prem users enabled for Dial-in conferencing must also have an Audio-Conferencing add-on license assigned in Office 365 before moving such users to Skype for Business Online. This means that the audio-conferencing add-on licences must be available in Office365 prior to migrating Dial-Conferencing enabled users


The meeting migration service can't be used if any of the following apply:
  • The user’s mailbox is hosted in Exchange on-premises.
  • MMS replaces everything in the online meeting information block when a meeting is migrated. Therefore, if a user has edited that block, their changes will be overwritten.
  • Any content they have in the meeting details outside of the online meeting information block won't be affected.
  • Only the Skype for Business meetings that were scheduled by clicking the Add Skype meeting button in Outlook are migrated.
  • Meeting content that was created or attached to the meeting (whiteboards, polls etc) won't be retained after MMS runs.
  • Meetings with more than 250 attendees (including the organizer) won't be migrated.
  • Some UNICODE characters in the body of the invite might be incorrectly updated to one of the following special characters: ï, ¿, ½, 􀳦.

Lync or Skype for Business Edition devices

The Lync or SfB Phone Edition devices MUST be updated to the minimum required firmware in your on-premises environment PRIOR to moving to Skype for Business Online. You can find minimum firmware requirements by clicking here. this document provided the Microsoft certified devices list.

If a user is moved from on-premises to online prior to updating the firmware, users will be unable to connect using their phones. To correct this problem, users must be moved back to the on-premises environment to have their phones updated to the minimum firmware.

Note: Do not attempt to update to minimum firmware or hard reset the phone prior to moving the user back to your on-premises environment. If a hard reset is performed while the device is not at minimum firmware, it will default to using PIN Authentication, which is not supported in Skype for Business Online or Teams.
