[Glass] Class migrations

[Dario Trussardi via Glass]

Ciao,

	i need to manage class definitions and migrations into GLASS deployment system.

	For now the only considerations i have do is relative to Gemtools auto migrate flag.

	If i right understand, with this flag enabled,  when i load from Monticello a package with a new class definitions the system create a classHistory of the class
	
	and migrate all instance to the new class definition.

	But if i renamed one instance what the system do ? How i can manage it?

	Anyone a some references about this problematic ?

	Where i found informations - example about this? 

	Thanks for any entry.

		Dario
