how to upgrade to lower version

Greating,

I have CSS11506 and current version is 07.50.1.03. I am going to upgrade it to version 08.10.2.05.

However, if the upgrade will cause any problem, I need down-grade to original version.

Could anyone advice me how to down-grade?

Does it use upgrade command again? if not, please advice me the procedure or URL.

Any comments will be appreciated

Thanks in advance

Re: how to upgrade to lower version

I have forgot asked another question:

currently with version 7.50.1.03 I have

Licensed Cmd Set(s): Standard Feature Set

Enhanced Feature Set

Secure Management

after upgrade to the version 08.10.2.05, will I lose the enhanced/secure feature?

do I have to requist new PAK number?

Please advice. Many Thanks.

Regarding the License issue, coming from 7.50 you should be safe.

If you encounter any issue, just email licensing@cisco.com with a 'show ver' and a 'show chassis'.

Hi,

http://www.cisco.com/en/US/partner/products/hw/contnetw/ps792/products_configuration_guide_chapter09186a0080405727.html

You use the same command to downgrade indeed. The CSS can hold up to 4 different images, so make sure that in the #show installed-software you have the two images you want to keep.

Once you have upgraded, if you want to revert back to the previous version, do as follow:

CSS# conf t

CSS(config)# boot

CSS(config-boot)# primary boot-file

CSS(config-boot)# reboot

If for some reason you experience an issue and cannot access the CLI, then use the OffDm as follow to recover:
