Upgrade NX5K

Hi all,

I need to upgrade a pair of NX5K due the bug CSCuq16049.

To prepare the the upgrade I want to run the following commands but I want to be sure that they don´t have impact on the service (high cpu or disrupt the services on FEX or the NX5K)

The commands are  the following:

show install all impact kickstart bootflash: XXX system bootflash: XXX - XXX is the new version
show spanning-tree issu-impact
show incompatibility system bootflash: XXX

Thanks and regards

Hi I have used those commands a few times as we upgrade regularly and never faced an issue , there in VPC anyway yes ?  so just do 1 switch at a time but you should be fine

Just to note we have issues with ISSU upgrades when your actually doing it have a window , we had an upgrade before came back with no incompatibility's but when it reloaded something went wrong with the ISSU and it reloaded each FEX 1 after another took a while as we had 22
