Does enabling Password hash synchronization in AD connect tool cause any issue in existing infrastructure.

Question

Hi experts,

I am trying to implement AD Domain Services in azure using the User forest method. I have the existing on-premise environment with AD connect running but the password hash synchronization is not yet enabled on it.

There are applications and services running currently in the environment.

I just wanted to know that if I go ahead and enable the password hash synchronization in AD Connect, would it create any outage, or is there any application or service that is known to create issues. Is there any chance of downtime or issue that might occur in the existing infrastructure?

Thanks.

Simply Enabling PHS disruption is minimal. I know when I have done it, no one noticed.
