I agree with you @Tal_Paz-Fridman , BUT, there is a difference between supported and recommended methods. All methods of upgrade are supported, but I am positive web UI is recommended way. Btw, I hope you are safe over there and I pray for peace. Sorry I keep repeating this statement, but I have to, because I lived in war literally half of my life, so it hits home for me, as they say.
I been all over middle east and Israel and you meet amazing people no matter where you go. I know that humanity will win at the end, because all people anywhere on this planet want is to leave in peace and respect.
