Difficulty migrating Wordpress to a subdomain of another domain. Why is he trying to get out of zero?

1. Migrate Wordpress site from one domain to a subdomain of the second domain to have a copy for modification.
2. Done: copied the files successfully imported database tables, the data written to the DB connection, queries replaced the old domain to the new subdomain in the records database. As always

Unexpected result: when you open any page on a new copy of Wordpress attempts to install from scratch. Prompts you to enter site title, user name etc. What am I doing wrong?

Solution
Gentlemen, I found the cause. The database was imported with the table prefix in lowercase, and config.php the prefix was specified at the top. At the same time in the database records prefix everywhere is specified with upper case - however, I believe, understand.
