Contacts – like Skype for Business client settings or buddy lists – will be migrated from Skype to Teams. External or connected partner contacts (Federation) will be migrated as well, but will not be shown in the client (as things stand). Skype consumer contacts will not be shown, as they are unsupported in Teams. The Skype for Business client will still be available for meetings, but customers will be unable to chat, place calls or access their contacts.
Microsoft has added a number of functions to Teams that are associated with Skype. They are shown here. But customers will not find all the individual functions of Skype for Business in Teams, as Microsoft sees Teams as an upgrade to what Skype was able to offer. Nonetheless, Microsoft is aware that customers are adamant that they want certain other functions and will prioritize these requirements via UserVoice.
Users are also advised to save the conversation history in the Outlook client prior to the update. Storage might not be required if a suitable configuration is already in place, but validation might be necessary. Microsoft is currently working on the client updates to ensure that conversation histories remain accessible after the upgrade to Teams. Customers are advised to refer to the Service Desk Guide for information in this regard.
Hybrid, Exchange and Teams
There are currently no plans for automatic upgrades of hybrid scenarios. Nevertheless, Microsoft urgently advises companies to consult with an authorized partner for assistance. There is also a reference document with information on things that need to be considered if Exchange and Teams will be connected.
Be aware: If a rollback is necessary, it needs to be managed via Microsoft Support. It is also possible to prevent or exclude migration. As things stand, customers can delay migration by 30 days, but a precise date by which the tenants need to have been migrated has not yet been set.
Teams will come with the same adaptable policies that were available in Skype for Business, for instance the CsClientPolicy or the CsConferencingPolicy.
Customers that are considering a connection with Enterprise-VoIP / PBX systems are urgently advised by Microsoft to consult an authorized partner, as Enterprise-VoIP does not permit any automatic upgrades. The same applies to CCE, as automatic upgrades are not available. In this case also, Microsoft strongly advises customers to consult an authorized partner to obtain the necessary information.
