@govpatel: On Debian (as per my original post). rename the .htaccess to what and how would that solve my problem?

@nicojulius: I did contact the server administrator. Says he doesn’t know WordPress and doesn’t know what WordPress needs / expects.

@govpatel: I tried that. Several times. With no luck.
They work under the default Ugly Permalink structure, but not under any other variation.

@nicojulius: Until now, the site was hosted under its own domain, using shared hosting at GoDaddy.

There have been no changes to the URL, or the database. Neither has wordpress been moved inside the domain. So, from the guide you point to, the move should as simple as the first option: “If database and URL remains the same, you can move by just copying your files and database.”
