This verb is intransitive, so it can be used of change of self but not of others. For change of others, use vista-.
One form of this word, wirne (PE17/191), is unclear in function. It is glossed “change” and could be a noun. However, it almost identical in form to the strong-past virne of virya- attested on PE17/189. It seems likely to me that this is the archaic form of the strong-past tense from before the change of ✶w- to v-.
Evidence elsewhere suggests the noun form of “change” is wistë.
