Downgrade Firmware Version XOS over switch x440

[Jairo_Rojas_Her]

I need to make a greater Downgrade to a smaller version on a switch extreme x440 , what is the procedure?
Keep in mind that the version I want to get the just installed because of an error and should give isntalarla because I have not even restarting the switch and these teams are in production.

Hello Jairo,

It looks like it installed just fine.If you are trying to install a different image then you just need to go through the same process you went through to get 16.1.3.6 on the switch.

Can you give us the "show version images" and "show switch" output?
