Upgrade to ISO XR 7.3.2

[mw79]

Hello,

I am checking upgrade documentation for IOS XR 7.3.2. I found that for some versions the bridge SMU CSCvw57276 is necessary before upgrading. So this means I need one additional step if this SMU is not yet installed. Is this also necessary (and supported) if I choose GISO method with "install replace" or can I ommit this step if I prepare a golden ISO?

Hi Mw79 , 

The CSCvw57276  SMU is needed beacuse of the new  iso structure in 7.3.x in XR .

When XR  software will be upgraded from lower version to 7.3.x version which  will have the new ISO  image structure,

there is need for Bridge SMU  CSCvw57276  in lower version to understand new image structure.
