Unified ACLs for v4 and v6

So Today I decided to upgrade my ASA5505 to Version 9.0(1).  Below are the steps to upgrade your ASA

First is to copy the file to the flash of the ASA

ciscoasa# conf t
ciscoasa(config)# copy tftp://192.168.1.3/asa901-k8.bin  flash:
 
(enter accepts what is in brackets)
Address or name of remote host [192.168.1.3]?
Source filename [asa901-k8.bin]? Destination filename [asa901-k8.bin]?
Accessing tftp://192.168.1.3/asa901-k8.bin !!!!!!!!!!!!!!!!!!!!

After the file has been copied to the flash memory of the routerFirewall do the following to have the device boot to the new os.

ciscoasa#
ciscoasa(config)# clear configure boot
ciscoasa(config)# boot system disk0:/asa901-k8.bin
ciscoasa(config)#write memory
ciscoasa(config)#reload

Done!
