We have an ACS box with all network devices configured to use TACACS for authentication.
If the switches and routers are configured to point to the ACS device,
can you delete the existing devices and add them with a differnet name with no issues?
As long as the device is configured to point to ACS and there is an account for it, it should use TACACS correct?
My thinking is I don't want to loose access to the device if it is remote and I cannot get to it right away.
