SFB 2015 OS Upgrade 2012R2 to 2019

Hi,

Just wondering what is the best way to go about upgrading the Server OS on our SFB 2015 Enterprise build

Can I do this by

1) DR each server in turn, but install Windows 2019, then re-install SFB 2015
or
2) Build up a new SFB Server pool running on Windows 2019, and then migrate my users to it.

Apologies if this question has been asked before.

Many thanks

Martyn

Hi @MartynNash-7451,
I changed the tag to office-skype-business-server-deployment, the reason why we recommend posting appropriately is you will get the most qualified pool of respondents, and other partners who read the forums regularly can either share their knowledge or learn from your interaction with us. Thank you for your understanding.

Hi @MartynNash-7451

It recommends you choose the second way to complete it. When you install Skype for Business 2015 in Windows 2019, please make sure Skype for Business Cumulative Update 9 or later. For more details, you can refer to:
