slimx you wouldn't want to use the importer for larger DBs anyways - it'd most certainly fail, no control panel can import DBs that big, not even plugin or anything else. Updraft Plus is the most reliable plugin for that that I've found (literally used it +1000 times), but it too craps out for anything over 1GB DB size... The best, besssssst by far is to just use SSH.
Steps are easy.
Using SSH, CD into the root directory of the site you want to run the import on:
cd /var/www/3b525ac5-54e0-4e54-9f8a-48b8410ffe53/public_html
Use FTP to upload the SQL file to that root directory (like the public_html or whatever). If you can zip it first you can reduce its file size to upload down by like 90%:
unzip file.sql.zip
Once the DB has been uploaded (if it was uploaded as a zip, unzip it) then run this:
mysql -u username -p database_name < file.sql
username = get the DB username from the site's config.php (assuming this is a WordPress site).
database_name = get the DB name from the site's config.php (assuming this is a WordPress site).
file.sql = name of your database SQL file
SSH will ask you for a password for the username you used, you can get the password from the config.php file too.
One last note, make sure the DB is empty before running the import. Meaning you might need to open the DB in phpmyadmin first, select all tables and drop them, then go to SSH and run the import.
