Query on SRV records while migrating from Lync 2013 to SFB Pool RRS feed

  • Question

  • HI,

    We have existing Lync 2013 one pool architecture with 24 sip domains. We have 24 SRV records created for sipinternaltls.

    Now, we are going for Skype for Business upgrade (on new hardware) in same topology. We will create 2 new SFB pools in pool pairing relationship. After deployment of SFB servers, we will migrate all useers from Lync 2013 to SFB Pools.

    We will have to create SRV records for all 24 sip domains pointing to our new SFB pools. I have a query on how we should proceed without impacting existing users on Lync 2013.

    Can we have 2 SRV records exist at the same time for each sip domain? Do we create SRV records for new SFB pools with higher priority so that connections goes to the Lync 2013 pool. After migrating all users to SFB pools, e can delete SRV record for Lync 2013 pool.

    Kindly suggest.

    Thanks

  • Why would you want to have two SRV records? There are many options to handle this cutover (from Lync 2013 to SFB)

    1. Keep Lync 2013 pool as SRV host name. Let the users be migrated to SFB and then change the SRV to point to SFB pool. in the meantime Lync server 2013 will keep serving 

    2. Change the SRV to SFB pool after ensuring that SFB pool is working fine. SFB will re-direct and register/authenticate request to Lync server 2013 if required. ... continue with migration.

  • Hi,

    The Lync\SFB Server support redirect function, so no matter these SRV records point to Lync Server 2013 Pool or to SFB Server pool, the FE pool will redirect it to the homed pool.

    So you can modify the DNS records according your record.

    Best Regards
