Cisco DNA delete old ISE add new ISE

[chris-doro]

We have installed new ISEs which have new names and ip addresses. 
But we forgot the entry in Cisco DNA 2.3.5.6-70143. 
I can not change the ip address of the ISE entry on DNA.
I also can not add new ISE because the menu entry is grayed out.
And when I try to delete the old ISE I always get error that old ISE is still used in network-profile "LAB".
But I've deleted all entries whith term "LAB".

"AAA setting cannot be deleted - Cannot delete AAA with IpAddress/FQDN - ise1.mylab.local as it is associated with Network Settings for Group - LAB"

Thanks.

Have you checked that it isn't still in use in the network settings(Design> Networks settings) somewhere?

With the help of the Cisco TAC I've found an entry under "Design - Network Hierarchy".
But then the next problem was, that I still got error message for "WLAN".
In some sites of the network hierarchy there still was the old ISE, even when deleting it on the GLOBAL level of hierarchy.
After deleting it step by step in every level of hierarchy, with additional troubles because of WLAN-profiles with "overlapping AP-groups in different sites" (the WLC was existing before the DNAC and I just discoverd it) I finally could delete the old ISE.
