I think you need to register a new bzrdir combination.


bzrlib.bzrdir.format_registry.register_metadir('views',
	'bzrlib.repofmt.pack_repo.RepositoryFormatKnitPack5',
	help='A WT format that supports views, and stackable branch...',
	branch_format='bzrlib.branch.BzrBranchFormat7',
	tree_format='python.path.to.my.WTFormat5',
)

Then you should have access to "bzr upgrade --format=views' (or bzr
upgrade --views).
