Can I upgrade directly from IMG: 16.1.3.6 to 21.1.3 on the Summit x460-G2?

The title pretty much says it all. Can I upgrade directly from IMG: 16.1.3.6 to 21.1.3 on the Summit x460-G2? I want to make sure their aren't any interim upgrades or patches I need to do prior. I searched for the upgrade matrix to this but couldn't find it. Also, should I be using the .xos or the .xmod file? What's the real difference? Thanks in advance.

You can upgrade directly from 16.1.3.6 to 21.1.3 on the X460-G2. You need the .xos file when installing 21.1.3.
Starting in EXOS 21.1, SSH is integrated into the standard EXOS image. There is no longer a separate XMOD module needed for SSH.
This is also carried forward starting with EXOS 16.2 and 22.1.

Hi Pierre,
Upgrading from 16.1 to 21.1 is supported. Just take some time to read over the release notes to see about known issues and such.

Regarding .xos and .xmod files, the .xos file is the actual EXOS image. XMODs are used to install additional features, such as openflow, ESVT, and SSH in some versions.
