Correct.

Basically setting the policy sets an attribute on the domain NC Head object
called maxPwdAge. That is the oldest password allowed in the domain. When
something tries to access an account, the system compares the pwdLastSet
attribute on the user object which maintains the absolute date/time that the
password was last changed with the current date/time as modified by the
maxPwdAge to see if the allowed age has been exceeded.

What you may consider is starting out with say a 180 day age and then every day
chop it down by a few more days and slowly expire everyone and get them reset.
