Attempting to help myself with an upgrade. I'm a newbie and I'm trying to get up to speed. I need to up grade my storefront, currently I have Miva and the upgrade to Miva 5 would be good and offer an quick/easy checkout with look & feel good. But Hostway does not and has no time frame for supporting Miva 5. What I'm I missing? Is there a big break up?

If I change one which would be easier to handle for a novice? If I change my storefront what happens to the traffic I get at the miva storefront page. Its good traffic, do I lose it if I change storefront software? I have been told its a major event to change servers, is that correct? Again, can a novice get through the process of changing servers? Any suggestions or ideas?
