Decommission of a pair of 6509's. The environment was broken up to Nexus 7004's for the cores, Catalyst 3750's for the end user edge, and Nexus 5k/2k for the server edge.

(update 1/2/2019)
Answering some of my most common critiques up front:
· "That's not a data center" - Not all data centers look like they're in a co-lo space. That room contains all the servers, networking, and other essential gear necessary to run the organization. Because of the equipment it housed we called it the data center.
· "The job isn't finished" - I agree. Unfortunately my career took me elsewhere before I could make more progress.
· "You should have done X instead of Y" - Possibly. The goal of the project was to decommission the old equipment and bring in new equipment. My approach was to bring in different equipment that allowed the environment to be managed more naturally through shorter cables.

I'm certain there are some other critiques. I'll update this over time.

Here is what I was doing at roughly when I was doing it:
00:00 - 01:01 Configuration documentation
01:02 - 02:20 Prepping racks for new user edge switches
02:21 - 04:09 Installing new switches
04:10 - 04:21 Unwrapping new cables
04:22 - 06:56 Cutting over to new switches
06:57 - 09:17 Removing old cables (user edge)
09:18 - 09:41 Removing old cables (server edge)
09:42 - 09:51 Prepping racks for new core
09:52 - 10:27 Relocating new core to new home
10:28 - 11:50 Recabling new core
11:51 - 15:26 Cutting service over to new core
15:27 - 16:31 Prepping to remove old core
16:32 - 16:36 Removing old core
16:37 - 19:14 General cable cleaning
