Webinar upgrade while live

[Renubhatia]

Hi community, 
Need an urgent help.
Is it possible that while I'm live on 500 participant webinar, the attendees increase and i've to increase the plan to 1000. 
Can I do it DURING my webinar is live?

I mean while my webinar is still going on, Can I increase the capacity by upgrading the plan?

Yes, you can upgrade the Webinar 1000 while your Webinar is still going on. 

Cheers!
