Спасибо за ответ и извините если спрашиваю слишком примитивные вещи.
Содержимое старого католога "..\htdocs" скопировал в "..\Apache\htdocs\home\test\www", так?
Потом из старого "..\MySQL\MySQL Server 5.0\data" беру папку "test_baze1" (эта база была создана до слёта системы перед установкой друпала) и копирую это папку (или не саму папку, а её содержимое?) в "..\Apache\htdocs\usr\local\mysql5\data" так?
А что дальше? Может нужно как-то указать связь сайта с базой? Потому что если сейчас я набираю: http://localhost/home/test/www/ то у меня открывается пустой сай без единой ноды или меню из того что было создано раньше.

Исправил в settings.php строчку:
$db_url = 'mysql://root:12345@localhost/test_baze1';
на:
$db_url = 'mysql://root:12345@localhost/usr/local/mysql5/test_baze1';
Сайт говорит:
Site off-line
The mysql error was: Incorrect database name 'usr/local/mysql5/test_baze1'.

Положил старый файл с базой в \mysql5\data
прописал $db_url = 'mysql://root:12345@localhost/test_baze1'; в settings.php
при запуске сайта http://localhost/home/test/www/
выдаёт кучу ошибок:
