How to redesign a site on Joomla?

Question

Joomla

remake the old one or create a separate domain and create a new one from scratch?
and when it is ready - replace the old site with a new one

on the product catalog site

Answer 1

Right on the working site, you can create/edit a new template.
At the same time, without changing the selected template in the admin panel - for visitors.
For example, you have the main template main_tmplt. It is selected by default.
You have installed and are editing the new template new_tmplt.
To see how the site looks on it, simply add to the end of the url of the pages:
?template=new_tmplt

Answer 2

if you are a little familiar with it , then no one will do better than you (better new + transfer / adapt the
Joomla database = this is a monster (convenient and open = yes, but for a beginner = this is HELL)))
if you don’t know how to save money)))
this is with regards the simplest projects
where the project is not 100syr = you need to hire a pro (so that you don’t bite your elbows later)))
from the free ones there is MaxSite = a good system, it’s never worse than a paid DLE

Answer 3

Correctly, and therefore effectively - buy a ready-made template that suits you as much as possible and slightly finish the css.
You need to do all this on a backup, of course, as you described.

Answer 4

You can do everything on Open Server so as not to buy hosting and a domain. And then when everything is ready, then transfer to the site.
Of course, after making a backup of the old site.

Answer 5

Make a local backup, layout the template, then install the template with overrides on the combat site. The main thing is that you have the latest version of Joomla and all extensions. Then there will be no problems. Approaches are different. Someone enters everything into the template, someone partially into the admin panel. Depending on this, it will be necessary to update the base on the combat one. I would copy and replace the new site, and update the database tables for the catalog from the old one. Then prices, catalog positions, work of SEOs (if any) will be transferred to the new one.
