Thanks esmi.

Following way worked to go from old domain to new domain:

1) Backup of all files of “abc.com” on my local PC
2) Exported DB of “abc.com” via phpMyAdmin to my local PC (.sql.gz – compression because phpMyAdmin didn’t let me export it without compression)
3) Created new DB for “def.com”
4) Uploaded files from “abc.com” and changed wp-config.php with DB data from step 3 / “def.com”
5) Open exported DB (the .sql file) with text editor – replace in line 123 (1, ‘siteurl’, ‘ENTER NEW SITE URL HERE’, ‘yes’), – and save the file as a new .sql file
6) Import DB after step 5 in the empty DB of “def.com” via phpMyAdmin
7) That’s it! Now you can login into “def.com/wp-login.php”
8) Go to https://def.com/wp-admin/options-general.php => change site-adress to “def.com”

Why don’t you create a new topic? ??

Can somebody come back to my question?

I am not going to rewrite content and just translate it, it will be two two different blogs, but thanks for your idea.
So do you have any recommendation about the structure of folders?

Sorry alchmyth, I was not concrete enough:
I would like to center the whole blog so that all posts + the sidebar are inside a box, and the space that remains shall be in another color.
So the result shall be sth. like this: https://www.mattcutts.com/blog/

I′ve tried to put an image to the background of my theme, but it only affects the header & footer section.

Okay I see alchymyth.
