This question: http://superuser.com/questions/596703/transfer-amazon-s3-data-to-mysql-database, was closed as Not Constructive. Before it was closed, I thought it might've made a good fit for dba.stackexchange.com, so I asked in The Heap and a moderator confirmed. I flagged the question for migration (I think I might have hit mod attention?), which was declined:

Asked in The Heap if they wanted this question. Mod said yes. Would probably do better there. – May 17 at 14:42 declined - flags should only be used to make moderators aware of content that requires their intervention

How could I have gone about getting a question like this migrated?

I realize odds are that if a question is not constructive on one site, it's probably not constructive on another, but this isn't strictly true (this is why I asked in the Heap.) Aside from Programmers being the obvious exception, there are questions that are on topic for Server Fault and not constructive, but work for Sec.SE. How does SSL work? for example. And while it might not be the best practice, smaller SE sites tend to be a little less aggressive about Not Constructive than SU, SF, SO.

Speaking specifically about dba.stackexchange, I think at least a few of these are arguably Not Constructive under our standards:

Should we periodically refersh the mirrored copy of a SQL server database?

Why are numbers tables invaluable?

Which is better: One database per application, or just one database?

Should I be regularly shrinking my DB or at least my log file?

Why is database administration so hard?

Which database could handle storage of billions/trillions of records?
