If you migrated to G Suite's email service, note that your old mailboxes created in hPanel will no longer work! However, you will be able to transfer your old email account's mail to Gmail with the old mailbox's details, which you can locate by visiting your old email account via the Check your old mailboxes button in the pop-up banner of the new mail section :)

Then, open Gmail and click on the top right Settings selection. Click on the Accounts and Import tab, and in the second section, select Import mail and contacts. Afterwards, you will only need to follow the steps on the screen and select the Start import option :)
