Debating aws, moving with fresh install or import?


I have been experiencing vps woes as of late. My vps seems to have mailers on their network and my server is acting sluggish.

So I have a question regarding aws comparability. Well, if aws is compatible anyway. I have heard people gripe about perma link malfunction, domain mapping. Etc.

On the other hand, if aws Works well, I would rather move now than later. Which brings up my second question: what's the best way to move?

I have used it as a development box which of course was dumb, so I have widget settings long deleted stored somewhere, etc.

Thoughts on the above please?
