Domain Mapping Workflow

Note: the installed plugin drop down doesn't pick up the Domain Mapping plugin, which is what I'm actually asking about

I'm about to start configuring the domain mapping for this site–which is a relaunch of the site at–and wanted to ask about a good approach to taking this site live.

There are a total of seven sites here, including the main one at The other six are new domains that haven't been used before. Here's what I was thinking of doing:

1. Enter the DNS information for the new sites only to point to the multi-site install.

2. Configure the domain mapping plugin to point to the correct sites (this is a sub-folder install, not a subdomain one).

3. Test those sites and make sure they're working properly.

4. Make the change to the DNS record for and test that.

Does this seem like a good way to go about doing this? What should I be wary of as I proceed?

Many thanks,
