Upgrade wallet db to v2 when blockchain is already v2?

[cross]

Instead of waiting the many hours that it was expected to take, I downloaded a recent v2 blockchain. But, I cannot figure out how to upgrade my wallet db to v2. Is that possible? Is there an invocation of chia db upgrade that will do that? Without arguments, it complains because I already have a v2 database.

all you have to do is del wallet DB
then start chia , wallet sync very soon
