    Hi @Garima Das

    If you want upgrade your domain controllers from Windows 2016 to Windows 2019 , you have check if the following prerequisites of domain controller under Windows 2019 are already configured :

    1. Domain an forest Functional level is Windows 2008 R2 or higher
    2. DFS-R is the replication system for sysvol folder
    3. Check if all you application support communication with a domain controller under Windows 2019

    If you choose to replace a domain controller Windows 2016 by new server with new IP , you should check the delegation on infobox to allow new IP to register automatically its DNS records.

    Hello Garima Das,

    Thank you for posting in Q&A forum.

    There are several drivers for application rationalization for organizations, mostly centered around reducing redundancies, paying down technical debt, and getting a handle on growing costs.

    This is not necessarily required. However, you can perform App rationalization depending on the situation in your organization.
