Hi eric.straw@wwt.com
I've recently upgraded a number of DNAC clusters from 2.1.2.X and 2.2.2.X to 2.2.3.5 and I have not observed any issues when creating IP address pools. Do you have any further details of the issue that you are experiencing? Does this happen when you create a new pool at the global level of the hierarchy, when you reserve a pool at the area/building level or both?
