For those who are migrating to a new server the purpose of the $500 is for the following:
* Credentialling the new server.
* Installing Amazing Charts
* Migrating your data from the old server.
There are three types of clients:
1. Those who know how to do all that or have access to someone like me who knows how to do all that.
2. Those who do not know how to do all that and do not have access to someone like me.
3. Those who "think" they know how to do all that, royally screw up their server, and then need a professional to spend hours sorting it all out then complain about the bill.
Number 3 and number 2 are the reasons AC has the $500 rule. And do remember, it's impossible for AC support to know which one you are. Even if you are number 2, it is still worthwhile for the support person to look your server over to ensure all is in good shape before heading off to the next client.
