entity framework - EF Migrations in Hierarchy -

i'm using entity framework multiple existing databases in hierarchy.

• 1x parent
• 3x children

i aim have 2 database contexts, 1 support parent , 1 support children. intend have automatic migrations setup , enabled on both contexts.

my child contexts pass in connection string name determine child connection create

/// <summary> /// represents child database context within hierarchy /// </summary> public class childdbcontext : dbcontext {      public childdbcontext(string name) : base(name)     {          database.setinitializer(new migratedatabasetolatestversion<childdbcontext, migrations.configuration>());     }  } 

question

will automatic migrations update each child database first time accessed i.e first time new childdbcontext("child1"), new childdbcontext("child2"), new childdbcontext("child3")?

i'm not 100% sure when migration check performed or whether work without parameterless contructor.

ef determines whether database needs initialized checking dictionary key generated connection type , connection string. migrations should performed each database.
