Yes.

i choose the protocol:https://lojafortnitept.com(only https://)or https://www.lojafortnitept.com(with www.)?

https://lojafortnitept.com shd be fine.

You need to export the following tables from the old database:-

xxxx_commentmeta (optional)
xxxx_comments (optional)
xxxx_links (optional)
xxxx_postmeta
xxxx_posts
xxxx_term_relationships
xxxx_term_taxonomy
xxxx_termmeta
xxxx_terms

where xxxx_ is your wordpress prefix

yes,the backup of the database will put the all tables

i can delete the other database right?

Only delete after successful restoration. Keep it for the time being

yes

is now importing to the new site

I already imported but nothing new appeared in the admin panel wordpress

Do not import yet.

Once ur sql files are ready, add the following lines before beginning of each table

The Wordpress prefix must match your current installation. The drop table must match the name of table being created.

i already import,u dont say this before,rip.
