Want to upgrade to get longer onZoom meetings, is moving from 100 to 500 participants the answer?

[JDE]

I have scheduled my first  onZoom meeting thinking it was 40 minutes long (my practice one was 40 minutes). But the window was limited to 30 minutes. I want to host a second of the same meeting, but would like to upgrade to get to be able to present for 45 min. to an hour.

I want to upgrade but no sure how to do that.

Will upgrading to 500 participants from 100 do the trick?

Thank you
