Sorry if this rubs you the wrong way... but why? Most people are still saying to stay away from 4.x.x.x and with the updates that are coming, they don't look like it will be compatible with the current OC 4 version so you'll be behind again.

And to say it again: don't build up currently a webshop with any of the 4.x releases!
Why?
Still too many bugs.

Second, if you really want a fully working webshop, it should run under php 8.x (at least 8.2.x).
For that you should use the 3.0.4.0 version: https://www.opencart.com/index.php?rout ... load_id=74
It works up to 8.4.x

Third: any update if not made manual, will fail!

In summary, when you still use 3.0.9.0, you should update to 3.0.4.0 because then you have a fast and stable base.
Later, when a stable 4.x (assuming 4.2.x) will be published, wait a bit and read through forum.
You can deside to update to 4.x when no further bugs are known.

p.s.: now you are a member of this forum since more then 5 years.
You should know how this whole thing works .. therefore you should also know already that using any 4.x version will not be a good idea.

And for commercial tasks like that (you asked for), we have a dedicated forum: viewforum.php?f=88
