    Hi

    My Skye for business infraestructure are:

    • One Front end server
    • One Edge server
    • One Mediation Server
    • SIP Domain:@domainA.com

    All clients logon with @domainA.com, but our business requirements is change SIP comain to @domainB.com.

    Which of the following is recommended proposals or what might follow to make migration?
    1. Is possible change SIP domain without reinstall nothing?
    2. I must add @domainB.com as additional sip domain and the clients can logon with this additional domain?
    3. It should prepare another Pool of S4B where used@domainB.comand migrate users with SIP@domain.com to @domainB.com Pool?

    Thanks.

    1) Yes

    2) Yes, add as additional domain, don't change default domain.  Change users over.  

    3) Not necessary.

    You'll want everyone to log out and back in, and send out notifications to anyone they may be federated with as those contacts may break.

    Make sure you add sip.domainb.com, and lyncdiscover records to the certs and ensure DNS resolves properly for new domain.  You'll need a seperate _sipfederation._tls and _sip._tls record as well which should point to sip.domainb.com externally which should point to your access edge.

    Hi Aocox,

    Anthony Caragol already provided you accurate and concise answers.

    As a supplement, please refer to following document which shows the step by step deployment:

    Lync 2013 Step-by-step: Add additional SIP domains in existing deployment

    http://social.technet.microsoft.com/wiki/contents/articles/30621.lync-2013-step-by-step-add-additional-sip-domains-in-existing-deployment.aspx

    Note: Although it describes Lync Server 2013, but same to Skype for Business Server 2015.

    Good day!
