Usually I stop the services (takes 5-10 min), HALT and then power up (it takes 10-15 minutes to bring the services up). So estimate a total of 20-30 minutes maximum of downtime until all the services are UP and Check the AD Connector if you use it. You can omit the HALT if you want.</P> <P>&nbsp;</P> <P>&nbsp;</P> Fri, 08 Feb 2019 20:34:20 GMT ajc 2019-02-08T20:34:20Z https://community.cisco.com/t5/network-access-control/how-long-would-it-take-an-ise-node-with-the-pan-psn-personas-to/m-p/3797985#M542672 <P>This is assuming you have a pair of ISE nodes and need to do this task for maintenance purposes. What is the time range expected in order to put this information in a MOP. Please let us know.

Usually closer to 15 min side before application services are all running.
