The best-practice on changing PCA password

Hi,

We have an upcoming activity to change the password of PCA from the dashboard. In past practices, we opted to change all PCA components' password at one go ie check all options available. At one instance, there was a network issue few minutes after submitting the password, which caused user unable to login to the PCA dashboard thereafter, and we had to call Oracle Support to resolve.

To deter this from happening again, I'm wondering if there is a best practice to proceed with the password change, ie do by component type, if so in which order of precedence, etc.?
