Saving user settings in LibreOffice to move them to another install

I intend to clear my 32bit Linux OS and install 64bit one, But I have a lot of customizations on LibreOffice Writer. For example autocorrect lists, macros, hotkeys, etc. How can I save all these so that I can recover them on the newly installed one?

I remember Ms Office automatically syncs such customization to an online account, so that they are synced automatically after reinstallation or on another computer.

You need to copy user profile to new installation (including all subdirectories and files):

Also look into menu Tools | Options | LibreOffice| Paths if you created your own files in this paths - or if you manually changed the paths.
