How is dark elixir distributed among storage buildings?

Question

I am a Town Hall level 7 and have a Dark Elixir drill but no DE storage yet. I have collected 2k DE until so far.

Now I am about to build a DE storage which can hold 6000. I need 10k Dark Elixir for the Barbarian King. My present DE, the 2k DE my DE drill has generated, is stored in the Town Hall. If I build a storage, will this DE stay in the TH or will it be transferred to the storage?

Answer 1

Once you build a DE storage, all your stored Dark Elixir, except those in the Clan Castle (Treasury), will be…

…split between the Dark Elixir Storage and the Town Hall in a 4:1 ratio, which means that the Dark Elixir available from the Dark Elixir Storage itself is four times greater than that available from the Town Hall.

Answer 2

Dark Elixir is not stored anywhere until you have a dark elixir storage. Reference : http://clashofclans.wikia.com/wiki/Resources#Dark_Elixir So I'm sorry to say, but your dark elixir has probably been lost.

Edit: Apparently I overlooked this section : http://clashofclans.wikia.com/wiki/Town_Hall At the resources available section, it shows that TH7 can store 2500 dark elixir. The dark elixir should be safe, the TH acts as a secondary storage, no dark elixir should be transferred.
