How to create a new website with an old domain name?

Question

PHP

Hello! There is a very old site and it needs to be completely updated. Put on the engine, change the design, structure, url, etc. You also need to transfer to a new hosting. Roughly speaking, a new site with an old domain name.
Tell me how to do it right?
What are the pitfalls?

Answer 1

This is a CSV string, you need this str_getcsv

Answer 2

You make a site in your locale, put it on the engine, change the design, structure, url, etc.
Transfer to a new hosting, roughly speaking, the new site will be with the old domain name.
You either send the old domain to a new hosting or transfer it too, roughly speaking, the only pitfalls are that you will lose indexing in Google.

Answer 3

Yandex does not like sites that have not been updated for a long time. I myself now have such a project, I don’t want to inflate myself in Yandex, I have very weak positions and I don’t want to grow in any way, although positions in Google are growing actively. If the site does not have a large number or strong links, then I would advise you not to waste your time and energy and immediately start a project on a new domain.
If you decide on the old one, then immediately set up redirects.
