Hi Community,

 

I need your help to perform an IOS upgrade, below is the current version:

 

c7600rsp72043-advipservices-mz.152-2.S1.bin

 

The needed version is:

This is about a dual SUP card as below:

Wow!  That is one big and significant DOWNGRADE.  

Are you really sure you "have to" do a downgrade?

If downgrade is required, read the Release Notes because you need to be very certain the line cards are supported at 12.2(33)SR train.

Thank you.

 

Indeed I have to do this in order to align the IOS version with other devices in the production environment.
