during intra forest migration and inter forest migration, what is the actual difference

let us say I am migrating and computer accounts from windows server 2008 to windows server 2012 or 16 in intra-forest
same way I am doing for inter-forest

does ADMT play the same role also the SID Accounts are deleted from source domain in same way

I think the difference is due to the forest name space. If migrating from within the same company  from to then thats intra-forest. So migration will be using the same forest schema and enterprise layout.

If migrating to a completely different forest e.g. to then I believe that is inter-forest. In this case the schema and enterprise layout will be completely different.

The migration is the same be it intra forest or inter forest.

Usually one would copy SID history when migrating, but not delete the accounts as part of the migration process, only delete the accounts after the migration has been tested.

@Peter Hutchison
" to" that appears to be two forests, did you mean " to" two domains in the same forest ?
