Learn Farsi: او پرسید که آیا می‌خواهم این اشتراک را ارتقا دهم. - He asked if I wanted to upgrade this subscription.

In Farsi reported speech, you do not shift the tense backwards like you do in English. You keep the tense of the original direct quote. Since the original question was 'Do you want to upgrade?', the Farsi sentence uses the present tense می‌خواهم after که آیا (if/whether), even though the main verb پرسید (asked) is in the past.

Is it mandatory to use both که and آیا together to mean 'if'?

In standard Farsi, yes. When reporting a yes/no question, که آیا (literally 'that whether') is the standard structure. In very casual spoken Farsi, people sometimes drop آیا and just use که with a questioning tone, but که آیا is the clearest and most correct way to express 'asked if'.

Why is the verb for 'upgrade' (ارتقا دهم) in the subjunctive mood?

It is in the subjunctive because it follows می‌خواهم (I want). As a quick refresher from earlier lessons: whenever you express wanting to do an action in Farsi, the second verb expressing that action must take the subjunctive form.

The subjunctive usually starts with بـ (be-), so why is it missing from ارتقا دهم?
