You will continue to receive dividends in your Vest account as normal, just as you did in your MyWallSt Advisory account.
However, if on the "record date" your stocks were in your MyWallSt Advisory account, the dividends will continue to be paid into your MyWallSt Advisory account and migrated to Vest in 30 business days until the end of the payment schedule for that dividend.
Note that they will appear as "Journal" in your transaction history because of the migration.
