<h2>Экспорт в MaxSite CMS</h2>

<p>Выберите автора для экспорта.</p>
<p>Я рекомендую экспортировать записи частями. Дело в том, что когда вы будете делать конвертирование, то скорее всего столкнетесь с ситуацией, когда ваш сервер ограничит размер памяти и файла. Чтобы этого не произошло лучше сразу разбить файл экспорта на несколько частей, а потом их последовательно конвертировать в <a href="http://max-3000.com/">MaxSite CMS</a></p>
<p>Следите за тем, чтобы размер выходного файла не превышал 300-500Кб. Количество можно подобрать экспериментально. У меня получилось примерно по 30 записей. После того, как вы экспортируете первый файл (с 1), то потом укажите начиная с 30, потом 60, потом 90 и т.д. Таким образом у вас получится несколько xml-файлов.</p>
