Dear TechNet Members
In our environment currently we have windows server 2008 R2 Active directory 3 DC at Head Office and 2 Domain Controller at DR site As per Microsoft End of support and End of Life we are planning to upgrade our DC's to Windows Server 2016 or Windows Server 2019
I need expert advice for the migration as I have my ROOT DC as on Physical IBM Blade.
I have below concerns
1. We have ROOT CA on Additional Domain controller
2. We have many application which still doesn't support TLS 1.2
3. Currently We are using Exchange Server 2013 CU 23 in our environment
4. We have 1000 plus users inside our Organization
5. Currently We are using SCCM and SCOM 2016
6. Symantec Enterprise Vault 12.3 & Symantec NetBackup as Backup Solution
7. Some Applications are directly connected to ROOT DC with ROOT DC DNS Name and its point of concerns for us.
I need some expert advise prior to migration so I will not miss out any point during the Migration as its very critical task for the organization.
