My wallet working well before and after update, staking work. I don't have any problem. I only move my .dat file from old wallet folder to new wallet folder and its working without magical commands in console 
I don't know how do you upgrade wallet's but it smell's unnecessary fud 
I don't know how do you upgrade wallet's but it smell's unnecessary fud mine (the new wallet) was fine staking yesterday, al of today though rejects on pos. had 2 confirm but they're not on the chain so i've deleted everything but the wallet and am waiting for a resync
