That's in the reference docs, see http://docs.neo4j.org/chunked/stable/query-set.html#set-set-a-label-on-a-node, you need to use set to a add a label to a existing node:

match (n {id:desired-id})
set n :newLabel
return n

If you want to add a label to all nodes with another label, just do `match (n:ExistingLabel) set n :NewLabel`. The existing label is not removed. – ADTC May 12 '16 at 02:31

Old labels can be removed using: `match (n:OldLabel) remove n:OldLabel` – Thomas Bindzus Sep 16 '17 at 10:43
