Setting up a mail server on fastpanel

Need help with the maintenance of several websites. Tasks: Transfer two small websites from different hosts to one existing hosting account. Both websites are currently hosted on different hosting providers. It is necessary to carefully transfer files, databases, and domain/DNS settings. Check the functionality of the websites after the transfer. After migration, it is important to ensure that both websites open correctly, pages work, there are no errors, broken links, or loading issues. Resolve the SSL certificate issue on the third website. The hosting control panel shows that the SSL certificate is inactive or expired, but the website opens as secure in the browser. It is necessary to check the actual situation, explain the reason, and, if needed, correct the SSL settings. Expected results: 2 websites transferred to one hosting. Both websites operate stably after the transfer. DNS/domain settings verified. SSL on the third website checked and corrected if necessary. After completion, provide a brief explanation of what was done. Important: Access to hosting, domains, and control panel will be provided after agreeing on the executor.
