AD upgrade and application integration.

I am preparing for an AD upgrade from 2008 R2 to 2016.  The question is do I need to be concerned with any applications that currently use AD for authentication.  Is it assumed that they will still work after the upgrade is complete?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

That depends on how the app authenticates. In most cases it should be a seamless upgrade. But some developers do strange undocumented things. Always best to check with the app support team to see if that is supported.

Ur assumption is correct
If u have old app which authenticate originally against 2003 ad, just make ensure it is compatible with 2016 ad, 99.99 % it will work but still....
