Any thorough documents on upgrading a set of 8500 series HA controllers with a large amount of AP's of various models?

I have completed the process but not without some hiccups. I had to piece together data from different documents. Basically, there is no information out there on what one can expect during the process and, as I mentioned in the topic, HA 8500 controllers with hundereds of AP's varying in model.

This is the most thorough document I have seen. The documents for 7.4.121.0 code was not as clear. I wish the documentation would give an idea of how long you should expect the process to take given a certain number of access points. Also, I have not seen any documentation stating that the controller is only reachable by console (in my situation anyway) during the AP predownload process. I was not expecting to not have access to the controller via SSH & GUI for over an hour. 

Thanks for your input!
