[Typo3] Server Upgrade

[Nate Russell]

Hello,

We have 3.8.0 installed and running on a Ready-to-Run Server from 
Schlund.de and we will be doing a server hardware upgrade in the next 
few days. We will have the same packet but we are just upgrading it to 
the latest version that they offer i.e. faster, bigger, better.

It was explained to me that the upgrade process basically entails 
schlund mirroring the HD with all files and databases to a new machine. 
I'm sure it is a bit more detailed and complicated than that but that is 
the gist of it.

My question is: What could go wrong?

All data and databases are being copied 1 to 1.
There will be the same names, permissions, paths and PHP/MySQL version.

New Proc is 64bit AMD. I don't think this is a problem at all but I just 
thought I would mention it.

I don't think there will be a problem aside from some possible short 
downtime due to the IP address changing.

Am I forgetting anything?

Thanks for the brain-picking,

Nate
