My production site is still on the previous CodeIgniter release and an outdated PHP version. I want it brought up to the current stable versions of both frameworks without disturbing any existing functionality—this is a straightforward core upgrade; there are no custom plugins or one-off modules that should complicate the process. Here’s what I expect: • Create a staging environment first, mirror the live setup, and run the upgrade there. • Take a full backup before you touch anything; I want an easy rollback point. • Update CodeIgniter to the latest stable build, resolve any deprecated helpers, libraries, or config changes, and verify the site runs error-free. • Upgrade PHP to the matching recommended version for that CodeIgniter release, adjusting server settings if necessary. • Push the tested code to production once I sign off. Send me one or two live CodeIgniter sites you have recently upgraded or built, outline the steps you’ll follow, and let me know the timeframe and fixed price you need. I’ll award quickly once I see solid experience and a clear plan. My website is www.successfulaustralia.com.au or https://www.successfulaustralia.com.au/
