Hello,

I'm running firepower 3100 cluster in native mode not multi-instance. must i upgrade the FXOS ? or it will be upgraded same as 2K

Like 2K firepower, fxos come with upgrades packages not need to upgrade separately as 4k and 9k.

Thank you for your help, i need a document for upgrading cluster not reimage.

But you mention you have native mode not multi instance' so not need to separate upgrade fxos.

To be sure ask TAC.

Thanks alot
