Best method is to dumpprivkey in V2 and then, importprivkey in V3.
It better not be a problem because that is exactly what the instructions say we can do. In fact, the first transition guide recommended it. It said to consolidate coins to one address by sending the coins to that address (instruction on how to do it were in the guide). Then dump the private key of the one address and import that key back into the V3 wallet.
Can someone provide a definitive answer on this? I also sent coins to myself to get everything into a single address. Of course when I imported the private key for the single address it did not recover all my coins but I was able to resolve that. My wallet says staking is active but I have seen nothing happen in over 14 hours. This could be normal but since someone else is having a problem I'd like confirmation that there is or is not an issue.
Thanks.
How many coins do participate in POS minting?
