Should I Upgrade from Laravel 8 to 9/10?

Hi developers,

I am currently managing an ecommerce (IT Hardware) website which is in Laravel. It is a live website which my company is using (not a company's main website, but an important one ), having more than 100K products. I wanted to know, should I upgrade this website from Laravel 8 to 9 or not?

And if I upgraded it to Laravel 9, how can I update that to my hosting without losing seo and without having critical errors?

I am the only developer in a company who is looking at this website.

If you help me, I will be very thankful to you!

Thanks in advanced.
