DeltaV Version 13 Max number of units allowed?

Gentlemen,

The max number of units in a DeltaV System is recommended to be 400 units with a license for 300>

What is the actual limit, I am doing an upgrade of an Allen Bradley System with 1400+  units.

I could do an import to test but I wouldn't know if there are other consequences, has anyone exceeded these limits and knows what the physical limit is?

Thanks and best regards

Chris
