Not totally sure what you are asking here.

If you migrate, you have to set the AD domain in Native mode. Native mode
prevents replication between AD DCs and *any* NT 4.0 BDCs on the network.
You can not go back from native mode. If you must have NT 4.0 BDCs on your
network you can NOT migrate.

If you upgrade you do not have to set your AD domain in native mode. It
remains in mixed mode. Mixed mode AD allows replication between AD DCs and
NT 4.0 BDCs. If you need to have NT 4.0 BDCs on your network, upgrade and
keep the domain in mixed mode.
