Catch Evolution Pro PHP Compatibility

My website colonialcarriage.org is hosted by GoDaddy currently running PHP Version  8.3.15. I am using Catch Evolution Pro Theme version: 3.5.4 GoDaddy is going to charge me an extended support fee for this PHP Version unless I upgrade to PHP Version 8.1 or newer. Can you advise if my current theme will function normally if I upgrade to the new PHP? Or let me know what I need to do to make my theme compatible? Thank you, Jennifer
