Hello Team,
Will ISSU support on DNAC Version 2.3.3.7-72328-HF5.
We tried to upgrade 9407R switches with ISSU its successful. But some switches not successful.
I see some cisco documents stating that ISSU not supported on DNAC version 2.3.3.7-72328-HF5

I have tried Cat 9500 with SVL deployment and Cat 9800 WLC - issu works for me.
as long as device matrix works that should works.
But some switches not successful.
This is need more information what switches they are ? and what version code running before and what verison code you looking to upgrade ?
what logs when it failed ?

the error complaining about the config - to proceed you need to remove that line and attempt again,
if you have concerns removing that command what is the impact,. better contact tac for confirmation before you proceed.
the one you upgrade success have same commands ?
