SharePoint_Config vs SharePoint2010_Config?

I feel like I'm going kookoo.

I have 2 SP2010 farms, one of them a new HA farm. The new one's config db is SharePoint_Config, the old server's is SharePoint2010_Config.

I haven't done an installation in a minute. I don't recall changing the names of the config dbs, or if there's even an opportunity to do so during configuration.

Any light to shed?

Thanks,

Scott
