On a migrate back to on-premise, the user lost all their contacts. Is this expected? Any way around it, or to force it?Ģ. We tried to troubleshoot this issue and found the AD attribute ‘msRTCSIP-DeploymentLocator’ did not update automatically. After migrating user to online and "after completion of AD SYNC as well" sometimes, we are not able to get the user logged in to SfB Client. Users share the same SIP as there SMTP address.ġ. For Example, the SMTP address is and the SIP address is, and rest 60% Avanzada 7 will also offer the update service to this new version.Currently, we are in a testing phase for migrating from LYNC 2010 to Skype for Business Online.Ĭurrently, we are having almost 40% of users who are having there SIP address different than their domain address. Move user upgrade: Used in case we can not interrupt the service and consists in installing a temporaty deployment of Lync 2013 where to host the users, services, endpoints and conferences while the update is done.Īt the end of 2018 the launch of Skype for Business 2019 is planned. The service would not be available during the update but it is the fatest way Offline upgrade: In this case, the servers with Lync 2013 automatically uninstalled Lync 2013 and installed Skype for Business 2015. If the updeate is to be made from Lync 2013 to Skype for Business we would use the option "in-place upgrade" in which we have two possible modes: Later, users, services and endpoints to the Skype infrastructure before decommissioning Lync 2010. If you want to upgrade from Lync 2010 to Skype for Business 2015, you would choose the "side-by-side migration" option, in which a new Skype for Business infrastructure is added to the Lync 2010 topology.
