Should all EHS36 be upgraded to 3.16?

Are they backwards compatible?

Meaning if its being used for a T46 today and we upgrade it and next week we move it to a T26 will it work or we need to downgrade?

Any reason Yealink never found a simpler way of upgrading it? (for example even a hidden GUI page that we can directly update to or URL..

Thanks!
