[inteldarvid]

hi team

Good day.

Could you help me please, I have some doubts with the update of the version for Catalyst 4500 that we have in the company.
I want to update the version to the recommended version of cisco. Can you recommend the steps to update a vss. For example I have the following commands:

I was going through the below cisco document and there are a few more steps as below: Is it necessary?

http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/ios/12.2SX/configuration/guide/vss.html#wp1169328

Router(config)# no boot system
Router(config)# config-register 0x2102
Router(config)# boot system flash disk0:image_name
Router(config)# end
Router# copy running-config startup-config
Router# redundancy reload peer
Router# redundancy force-switchover

Do you also recommend me to update the rommon?

I attach switch data:

i followed below steps and works as expected :

Make sure take config backup out of the box
Read the release notes
perform the task in maintenance window

1. Copy the New image to Switch
2. configuration register value 0x2102
3. check the image in both the device :
show bootflash:
show slavebootflash:
4. veryfy the image :
verify bootflash:iosxe.bin
verify slavebootflash:iosxe.bin
5. remove old boot image
no boot system flash bootflash:oldiosxe.bin
6. change the boot variable :
boot system flash bootflash:iox.bin
7. config register
config-register 0x2102
8. verify boot variable
show bootvar (make sure new image in the variable)
9. save config
write memory (give 5min make sure config sync correctly)
10. reload VSS (if you good downtime)

Thank you so much dear for your response.

Dear I have a last questions. Can I upgrade  only imagen XE? or it is also important to install the rommon software? Thank you

Since you have not mentioned what is the target version you going to., 

If you decided, my point mentioned part of the list :

Read the release notes

which will give you direction - is the ROMMON upgrade required or not required? (it will depend on the target version of code you choose to upgrade)

I have pasted the latest cisco recommendation version and release notes : (Upgrading the System Software)
