Hey Thomas,

Thanks a lot for this video.  Have a question on the Split upgrade option.  If we have six nodes to upgrade (2 x PANs, 2 x MNTs, and 2 x PSNx), can we go through the Upgrade Wizard and follow those steps and split the in several maintenance windows (i.e,, if we start the Upgrade on Tuesday and performance the Split Upgrade by upgrading the secondary PAN first and then next node ..etc following the Split Upgrade wizard and then resume the upgrade the next day for the the other nodes..)? Not sure if we can go back to the upgrade wizard window or if it will time out after idle session). 

 

Wondering if we can perform the Split Upgrade in three maintenance windows and pick up where we left off from the previous day.

 

thanks in advance!

@latenaite2011  Yes, you may do it in batches. The picture below shows that a 2-node ISE 3.0 Patch 2 deployment being upgraded to ISE 3.1 with only one completed while the other has not started yet.

PS: You cannot make any configuration changes in the Admin Portal until the upgrade process is complete.
