Is it possible for us to upgrade Lync Server 2013 to SFB server directly without going through SBF server 2015

Sure. You can upgrade from Lync server 2013 to Skype for Business server 2019 directly.

Hi Sharon
Thanks for your response, do you know some unknown risks about this kind of upgrade we need to pay more attention to?
@Andy Ji ,
Please note that the article which I provided in my last reply does not address every possible legacy deployment topology or every possible migration scenario. Therefore, you may not need to perform every step described, or you may need to perform additional steps, depending on your deployment.
