Hi, I am going to update my SG220-50 50-Port Gigabit Smart Switch, the device is in version 1.0.0.18 and I will update it to release 1.1.4.5. Can I update it directly?

I need your help, I am going to update to the version recommended by Cisco Release 15.2.2E9 MD but I don't know which file to use, if the bin or the tar, what is the main difference, which one should I use?Thank you

For catalyst 2960S I will update it to version 15.2.2E9 (MD) does anyone know if there is an update path that I should follow or can I update directly from any version to version 15.2.2E9? I appreciate your help, regardsSwitcSwitchinghin

do I have to disconnect all the devices that I have connected to the switch ports to update the IOS version?

I have a question, do I have to disconnect all the switch ports to update the IOS version?
