Native to Hybrid Configuration Conversion

[furrow.s]

Hello. I think I already know the answer to this but I want to get an idea if there are any easier ways about it. We have a Catalyst 6509 running Native IOS that we have been having issues with. We are replacing it with an identical 6509 and plan to load Hybrid CatOS on it. Are there any easy ways to convert the configuration from Native to Hybrid. I've heard of conversion utilities to go from Hybrid to Native but not vice versa.

Any help is greatly appreciated!

I don't have an answer for you but I would like to hear your problems if you have time since I will be migrating from Hybrid to native for my 6509s soon.

I just curious what is main reason for you to migrate from hybrid to native.

Got Cat6509 running fine with hybrid thus far.

Thanks

Couple things I need to warn you about. The Hybrid bootflash is not necessarily compatible with Native and may have to be formated. You could also run into problems with NVRAM, which may also need to be formated. I converted about ten 6509s from Native to Hybrid using this method:

From Native Mode:

-copy disk0:c6msfc3-psv-mz.122-14.SX2.bin bootflash:

-conf t

-conf 0x0

-wr

-reload

From ROMMON:

-confreg 0x2102

-boot disk0:cat6000-sup720k8.8-2-1.bin

From CAT OS:

-format bootflash:

-copy disk0:cat6000-sup720k8.8-2-1.bin bootflash:

-set boot config-register 0x2102

-set boot system flash bootflash:cat6000-sup720k8.8-2-1.bin pre

-set sys high en

-switch cons 15

From router ROMMON:

-confreg 0x2102

-priv

-nvram_base #######

-nvram_erase #######

Note: nvram_base will give you a number. Use that for the nvram_erase. May have to repeat this twice.

-200000

-boot bootflash:c6msfc3-psv-mz.122-14.SX2.bin

From Router:

-conf t

-config-register 0x2102

-boot system flash bootflash:c6msfc3-psv-mz.122-14.SX2.bin

-redundancy

- high-availability

- single-router-mode

-end

-wr

Other notes: You only have to go into the priv mode if when you try to wr and get an error about nvram. Proceed with caution whenever in ROMMON and especially with priv mode.
