Now that http://dba.stackexchange.com is there, shouldn't we divert the relevant traffic there? I was specifically thinking about tags like mysql or sql-server which explicitly state that DBA questions are on-topic at Serverfault - this seems counterproductive to me. Should not we at least modify the description to directing the users to DBA?

Edit: since there have been a couple of close-as-duplicate votes, I believe there is a misunderstanding - it is not so much about deciding where questions go but about telling users *"consider posting your database-related questions to http://dba.stackexchange.com after reading their [FAQ](http://dba.stackexchange.com/faq)"* in all database-related tags.

E.g: the [sql-server tag description][1] explicitly states:

> - Who would use the code that my question relates to the most, a developer or a DBA? If a developer, Stack Overflow is your place. If a
> DBA, ask away here.

which it should not, in my opinion.

[database-administration][2] does not have any description at all, but the name alone is kind of a hint that questions tagged with it would be on topic at DBA.
