I am doing autoscaling for updating ami images

what i am doing is

1. double the instances(new will have new instances have new ami)
2. new instances are up and running but i see that their lifecycle status is pening:wait(as per the documentation its default timeout is 1 hours and after it goes automatically to next step)

How would i move to next state, without waiting for default timeout once my applications are deployed to the new instances

and i want to go to the next step, without waiting for timeout, how would aws instance know that the software/applications deployment is done do i have to mannulay tell it then how

Write now i am just waiting for one hour(timeout)
