Can i save a WP setup and transfer all the setings for another project?

Various people do “WordPress cloning” plugins.

backup buddy for instance. it’s paid tho.

You can backup the database:

Then manually change the siteurl and home values to the new domain:

Sounds like a good way to do it, thanks James
Do i need something from the files to transfer over?

From your description, it sounds like you’ll only need the plugins at /wp-content/plugins/ .

After doing quite few sites like that without any problems, today i found something.

When you add a gallery and set it to show each picture in its own page, it uses a dir from the old domain

here is the url to the page

https://newdomain.com/oldomainnamedir/attachment/picture-1/

records for “olddomaindir” are found in the “wp_options” table

option_id blog_id option_name option_value autoload
531 0 rewrite_rules a:208:{s:159:”^(it|ko|zh-CN|zh-TW|pt|en|de|fr|es|j… yes

in the “option_value” column

how to fix that without replacing all the rewrites or deleting them, since there are quite few from the plugins which i guess i need

Ive seen quite a few people use this plugin with success after moving wordpress installs
