I have a client who has a new Catalyst 6509 that came shipped with CatOS on it.  He needs it upgraded to IOS so that it looks like his existing 6509 that's already in production.

I don't know much about CatOS and could use some direction here.

There's about 10 steps to migrate from hybrid to native mode. Here's the Cisco procedure:

However, if you don't want to use the Cisco method...

1. Make sure the native mode IOS is on an accessible flash device (in this example, I'll use slot0:)

2. Change the Supervisor card config-register to 0x0 which forces it into ROM Monitor.
P4-6006> (enable) set boot config-register 0x0

2. Reboot the switch using the reset command

3. Remove the CONFIG_FILE variable to prevent problems saving the configuration.
NOTE: THIS COMMAND IS CASE SENSITIVE!!!

rommon 2 > CONFIG_FILE=
rommon 3 > sync

4. For the new environment variables to take effect, the switch must be rebooted.

rommon 4 > reset

5. Load the Native mode IOS.

rommon 1 > boot slot0: c6sup12-jsv-mz.121-12c.E2 (example filename)

6. It will take at least 60 seconds before you see any indication the switch is loading.
Once booted, configure the switch to load the IOS on power up.

Router>enable
Router#conf t
Router(config)#no service config
Router(config)#boot system slot0:c6sup12-jsv-mz.121-12c.E2
Router(config)#config-register 0x2102
Router(config)#end
Router# write mem
Router# reload

Thanks.  How would I do this entirely from TFTP?

For example... I want to download the IOS software from the production 6509 via TFTP, then upload it to the new 6509 (to replace the CatOS) via TFTP.

What would be the steps to do that?

Well, from the existing 6500, you would do a "copy <device>:<filename> tftp"

Then copy the IOS from the TFTP server to the flash on the new 6500, "copy tftp <device>:<filename>.

Okay, almost there.  How do I know which device the system is booting from?  Should I assume slot0 or is there a way to check?

And are your 6 steps above all I need to do this?

The switch will boot from whatever device you tell it to boot from with the boot command. Either bootflash, slot0 or slot1. (depending on your sup, it may be disk instead of slot)

Right, so how do I determine where it's booting from?  Is it "show boot" or something else?

You mean the existing switch? "show version" and look for something like:

System image file is "slot0:c6sup12-dsv-mz.121-13.E3"

In this case, it's booting from the file "c6sup12-dsv-mz.121-13.E3" located in slot0.

Thanks !
This has helped me out to understand how to convert the OS. But, what happens to the config file programmed in CatOS and you are in the process of converting the 6509 to IOS? What are the steps I should follow to convert the config file to IOS?
