Can't change IP address on device - Very frustrated

I'm having a small but frustrating issue. I need to change the IP addresses on several of my devices and Zenoss will not let me because those IPs were used before. Unfortuneatly we played a bit of a game of musical IPs last night and Zenoss is not happy about it. Here is the deal:

 

Here are the actual network (not zenoss) changes we made:

  1. We removed an old device we'll call Router1 (10.0.0.1).
  2. We then reconfigured one of our existing layer 3 switches to replace Router 1 and gave it Router 's ip address. (10.0.0.1)
  3. We then stood up a new firewall and gave it the ip address that that the layer 3 switch used to use. (10.0.0.2) (Yes yes, i know its silly, but thats what we did)

 

 

When i sat down at Zenoss the first thing i did was place the old Router 1 device into the "Decommissioned" production state. I still wanted to keep its perf data and events but i didn't want to actively monitor it anymore.

 

I then went into my layer 3 switch device and tried to change the IP address to 10.0.0.1. Zenoss wouldn't let me. Thinking that perhaps Zenoss could only have a "one device to one ip address" ratio i went into the decommissioned router and changed its IP address to 0.0.0.0. (I also tried several other arbitrary unused ips) Zenoss still would not let me give my layer 3 switch the 10.0.0.1 address. After some forum browsing i found that apparently the ONLY way to get that ip address back for use is to entirely delete the old device that used the IP address i want to use now. So, with a bit of reluctance that's what i did. As soon as i did that i was able to give the layer 3 switch the old router's ip. All is well with the layer 3 switch now

 

Lastly, I tried to add my firewall to Zenoss using the layer 3 switche's OLD ip. But no. It won't let me. It says its still in freaking use.

 

Seriously? I can't be the only person who thinks this is absurd. I want to keep all the perf and event data for the layer 3 switch. I don't want to have to delete it entirely and recreate it just so that i can add my new firewall device into zenoss using its OLD ip address.

 

Any help would be greatly appreciated.
