I am looking for a competent professional who can help me upgrade the PHP version of my current website from 7.3 to 8.3.

Key tasks:

- Assess the current website structure, content and possible custom functionalities (if any). Since I am not sure whether there are any specific, custom-built features present in the website.
- Upgrade the PHP version to 8.3 without causing any breakdowns or loss of content or functionality.
- Thorough testing post-upgrade to ensure stability and full functionality across all elements of the website.

This task exclusively requires a PHP upgrade; I am not seeking any other changes or updates to the website at this time. Note that I don't have access to the original source code of the website, so the freelancer will need to adept at working around this limitation.

Experience in working with websites built on various platforms and the ability to navigate potential custom-built features is greatly beneficial. Proven track record in troubleshooting and bug-fixing is a must, as is the ability to work meticulously to prevent and resolve any potential issues that might arise from the PHP upgrade.
