Простой скрипт, который позволяет мигрировать набор виртуальных машин (их конфигурацию и диски) с одного СХД и сервера на другой, основываясь на их текущем положении и названии.
К примеру, у нас есть наименованные по стандарту VM какого-либо проекта (в данном случае имена содержат *HYD*) и нам известна конечная точка, куда их надо перетащить.
Порядок работы скрипта следующий:
1. Получили массив имён нужных нам VMs;
2. Получили имя хоста виртуализации на который будем двигать VMs в переменную;
3. Берём из массива конкретную VM и находим её местоположение, сравниваем с целевым, если текущее положение VM не равно целевому, то делаем операцию Move.
4. Спим 5 секунд.
Работает для Windows Server 2012 (R2) и SCVMM 2012 R2
