How to change the role of ISE?

[JustTakeTheFirstStep]

I would like to change primary and secondary of ISE Admin Node.

please tell me how

@JustTakeTheFirstStep you must do this from the web GUI of the Secondary node, navigate  Administration > System > Deployment > Click on the "Promote to Primary" button.

Beware the ISE services will restart.

I can't find the "Promote to Primary" button.

@JustTakeTheFirstStep no, you need to login to the Secondary node web GUI in order to promote to primary. From another tab in the web browser connect to the IP address or FQDN of the Secondary node and login, you can then navigate  Administration > System > Deployment > Click on the "Promote to Primary" button.

I found that button in the secondary node.
If I remember correctly, the ADMIN node was ISE1.
It looks like the ADMIN node has been changed to ISE2. Can you track the history?
