Removing a wordpress multisite installation and preserving the database before migrate to nginx

Hello, I have a wordpress multisite installation, and I need to remove the multisite, and keeps just the site ID 5 ( in the main address ( So I follow this tutorial to remove wordpress multisite installation:, after that I dropped wp tables post, terms, term_taxonomy etc, and changed the tables wp_5_ to wp_. My site became extremely slow to open pages, his aesthetic was greatly affected, images did not load, so I was informed about the serialized data in the database, and that I should not change the database manually.

I do not intend to migrate the multisite to nginx, just a single website (ID 5), so what is the best option to preserve my data?

p.s.: I’m disregarding the option of buying a plugin to do this, and learning to do at hand.

I think I have 2 options:

  1. do a stand alone installation ( in, and after redirect .com to .com/br), and stay with a single website.

  2. change the database tables from site ID 5 to the main site tables database (I mean keeps just one database working perfectly), and migrate a single website.

Which do you recommend, and can you provide references on how to do this?
