Hello,
I am planning a manual failover from Active to Secondary.
And in order for the Primary to become offline, I was wondering whether it is sufficient to shut down its network interface.
Next, the role of the Secondary has to be manually set to primary by assessing the GUI of Secondary visiting Administration > System > Deployment.
Before I am doing this, how am I able to make sure that the secondary is in sync and to be able to operate as primary.
ISE version: 3.0_061722
Please advise.
Thanks,

"0 messages to be synced" means both nodes are in sync.
below are few examples of messages and data that are typically synchronized between the primary and secondary nodes:

you don't necessarily have to shutdown primary to promote secondary, you can do it anytime.
to check Sync hover over on the information icon next to node status on deployment page , it will tell you if its in sync.
If you do need to shutdown primary a graceful way would be to SSH into primary and shutdown application with "application stop ise" command then you can shut down uplink to ISE.

Thank you.
When hovering over the information icon as it has been suggested, the primary shows a Message Count of 25644310, while the secondary shows "Sync Status: 0 messages to be synced".
Is it fair to say that both nodes are in sync, but currently there is no need for sinking any messages?
And I am also wondering what type of messages will be synced between the primary and secondary?
Please advise.
Thanks.

All messages will be synced, these are just counts for replication. How many ISE nodes do you have? Two?
