Thanks Jimmy, for your kind attention and providing the information.
I have gone through that document; however I didn’t find specific info as such which says a fresh installation is the recommended or suggested process. Yes, it does talks about installing SFB 2015 on 2019 Server OS with Cumulative Update 9 or later. Could you please help me to understand why you have come to the above conclusion?
Yes, the conclusion is not from the document provided. The official document is not provided the detailed steps about how to upgrade the Skype for Business OS. But I have met the customer who asked the same question before. He followed the above suggestions and succeed.
Considering the In-place upgrade may affect the Skype for Business Server, we still recommend you build a new server and migrate the user to the new server.
Thanks again :) building a new server is going to take some time for sure, is there any process i can adopt where i can reduce the whole effort needed to build server manually?
You need to notice this requirements when you build a new server:
1)All servers within a pool must run the same OS.
2) Paired pools must run the same OS.
For more details about discussion, you could refer to this blog's steps.
Just checking in to see if above information was helpful. If you have any further updates on this issue, please feel free to post back.
definetly that was more than informative. i think i have not found any microsoft document which clearly talks about OS upgrade process. Neither they say you can't do that. thanks a lot buddy :)
You're welcome!
This article describes you how to upgrade the OS from 2012 R2 to 2019 for your reference.

После обновления Windows Server с 2012R2 до 2019 не стартовала служба переднего плана Skype for business.
Остановить службы скайпа.
В панели управления удалить обновления S4B кроме самого первого, которое устанавливалось при развертывании сервера S4B. (CU 5)
Почистить Managed API 5.0 оставить только самую первую (старую)
Далее в "Программы и компоненты" удалить все компоненты S4B "Основные компоненты S4B", "Сервер веб-конференций", "Сервер переднего плана", "Сервер-посредник" и т.д.
Перезагрузка сервера.
Остановить службы скайпа.
Запустить мастер развертывания skype for business 2015. "Установка или обновление системы S4B" -> "Установка или удаление компонентов Skype для бизнеса Server"->"Выполнить".
Он переустановит компоненты S4B.
Опять перезагружаем сервер.
Устанавливаем последний Сumulative update skype for business 2015. (2 файла "UcmaRuntime"и "SkypeServerUpdateInstaller") В нашем случае CU13
После очередной перезагрузки проверяем работоспособность Skype.
