WP multisite development staging

[mattada]

We dont do a lot of WP multisite projects, but have a bigger one coming up.

What are your suggestions on a development environment for testing, staging and later deploying a wp multisite using the subdomain url hierarchy? Right now the current genius idea is to just buy a new URL. Somesite-beta.com style. I feel thats not the right answer.

thanks!

Why not double subdomain it? subsite.beta.domain.com and anothersite.beta.domain.com
