Moving hosting providers

In June I am moving to a new hosting provider. This is going to save me a lot of money because the new hosting provider (1984.is) is a lot cheaper then my current host provider (Hostdime U.S). This is rather complicated move because I am moving completely new system. This can result in technical problems and downtime. I hope to minimize this but it might not be possible avoid this.

The new hosting provider is located in Iceland and I now only pay $9,91/month (sign-up offer, its $10,75/month from next year) for the hosting compared to $235/month that I have been paying.
