Temporary URL?

Sorry if I've missed the answer to this question, but I've certainly searched the wiki and the forums:

I want to transfer sites from my old server to my new dreamhost account, but I don't want any downtime. I can transfer the files, and setup the databases easily but even so, I might make a catastrophic error along the way. So I need WWW access *BEFORE* I change the nameservers, so I can check those sites are operational first.

As I'm on paramount.dreamhost.com, can't I access my sites using some alternative, temporary address? Like http://paramount.dreamhost.com/myusername/mydomain.com -- if you see what I mean?

I've tried various possible address combinations but not hit upon a predictable one yet.

Many thanks

This should do the trick:

http://wiki.dreamhost.com/index.php/DNS_-_Viewing_site_before_DNS_change

Thanks. Don't know how I missed that. However, they're still very difficult instructions to follow.

I've tried to add a subdomain to dreamhost.com and paramount.dreamhost.com, but I just get:

"Can't add domain: you don't have permission to add to dreamhost.com"

:(

The free sub-domains are on dreamhosters.com -- not dreamhost.com.

Doh! I'm blind as well as totally unable to use a Wiki. Thank-you. :)
