Migration to Magento - never expected issues happened

Couple of weeks ago our team made a webinar about migration to Magento. But really we lost one critical thing.. And the life is really teach itself. Please first of all you have to read hosting reviews.

Recently we tried to move our customer website to Magento. It was really done carefully and Friday evening we were expected to have a rest over weekend. But 1and1 decided that we have to work over time and simple drop all information from the server including databases, website. 

The whole server install was refreshed from scratch with no reason. So kindly - before you do migration - just spend some time to research hosting reviews.
