Because of resource and performance problems I want to move my website from Shared hosting to VPS. In this process, I also want to migrate from PHP 5.6 to PHP 7.4. Therefore I need to re-code the PHP scripts. So I need time for my own on the new Plesk server to get things done.
I have the next steps in mind:
There is a deadlock situation, however.
Of course, this is done before by many developers, but how it's done? Does anyone know? And which other problems can I expect?
Purchase a wildcard certificate or create one by letsencrypt And use a subdomain like test.yourdomaine And point it to your reverse proxy vps new ip
