I have downloaded a new wallet so I may need to wait for this migration process to check again. As of now, still, my account balance is zero.
So did you used "the light-wallet" back in 2017 or did you store your Seed in "Trinity"? Maybe, the best idea is to join the official IOTA Discord.
There you will be taken for sure if you describe your problem precisely. Please just be careful not to share your seed with anyone. Even if you should be contacted via PM there.
