Hi,
I am planning on promoting Cisco ISE 2.3 Secondary admin node to primary, it is an 3495 appliance, my question is do i have to do a manual sync up before i promote it and my radius traffic which is currently being served by 4 PSN's will that be disrupted when my PAN restarts?
Please Advise.
Thanks

Just make sure that the status of all your nodes is healthy and online, there is no need to do manual sync up.
In regards to the RADIUS auths on PSNs , they will not be disrupted, you just loose the ability to make changes and administer the deployment while the secondary admin node is being promoted to primary.

Hi,
The Primary PAN and Secondary PAN should be in sync all the time, unless an issue. No harm running a manual sync before promoting Secondary PAN to Primary.
During the period the old P-PAN is down and the Secondary is being promoted to be the new Primary PAN, the database would be offline for a period. Check out this section in the ISE Admin Guide to confirm what will and won't be effected when the PAN is down.
Depending on what services you are running on the PSNs you might find you will not impact authentications, but it might be wise to promote the PAN out of hours.

Hi All,
I personally experienced directly, when you are a design in redundancy Deployment ( 2 Node HA) in which you are PAN/MON/PSN on the same node, I can confirm the Both Node restart and this cause the outage service.
