Will my theme be ruined if i upgrade wordpress

What theme are you using?

i am using Eclipse pro version 1.0.9

You’ll really need to check with the developer of your theme – as we don’t have any information about commercial themes here. Look like it’s here: https://cyberchimps.com/eclipsepro/

Also, it’s always a good practice to make a complete backup of your site and database before updating – so that would give you a fallback just in case.

WPyogi, can you please suggest/link-to the best-practice ways to backup a website and WP database? Do you suggest using plugins, or manual techniques?
