Hi All
I would like to give me some information about migration how many data migration templets are their in ax 2009 and 2012 what is that
You can go to administration, & there you get the Excel migration & definition group(.Dat & .Def) file kind of migration.
I suggest you look at DMF for data migration in AX2012.
What I will say is out of the box AX by itself comes with zero data migration templates.
