https://www.abeille-cyclotourisme.fr/ has been online since about year 2000. It is a 2.5 GB website used by my bicycle club, with HTML4 pages and CSS2, entirely hosted at the root of a single directory (containing many sub-directories) here at Dreamhost.
Under the same domain name, I plan to create with my successor webmaster a new website for the exact same purpose, this time using Joomla or WordPress (my succesor's choice) to be more modern, with a Start-up Date within the year 2020. I don't know the first step I need to do.
Before Start-up Date, I currently assume, based on my searches on the web, that the new website, under construction and not advertised (closed to robots), should be visible on the subdomain www.2020.abeille-cyclotourisme.fr. Meanwhile, I want the old website, still updated, to continue to be accessible from the current domain www.abeille-cyclotourisme.fr.
After Start-up Date, I want the new website, then solely updated, to be visible on the domain www.abeille-cyclotourisme.fr. Meanwhile, the old website, no longer updated, would continue to be accessible from the subdomain, advertised and open to robots, www.2000.abeille-cyclotourisme.fr.
There would need to be a minimal number of links (about 10) from the new site to the old site and vice-versa.
On another forum (mac-forums), I was advised to just make a new directory in the root of the current one and put all the new files in that directory for the new site. The links between them could easily be put on what ever pages I want them on. That's just the easy way. Just continue to make the new site in the new directory (and test it there) and when it is ready to go live put the index file for it in the root and rename the old index file.
This looks like an interesting proposition that I would gladly follow were I to continue making the new website by hand (text editor and FTP client). However Joomla or WordPress may prefer their own piece of server real estate and may resist a pure directory/subdirectory approach as above.
can I, indeed, avoid my domain/subdomain initial approach and rather just make a new directory in the root of the current one and create inside this new directory a Joomla (or WordPress) new website and instruct the Joomla-robot to put all its new files in that directory for such Joomla new site ? Or do these robot site builders like Joomla or Wordpress need their own piece of server real-estate close to root to live and prosper and feel offended (prevented from working efficiently) at being surrounded by alien hand-made files and folders ?
Alternatively, what would I need to do to implement my initial Domain/subdomain approach ?
TIA for any suggestion.
