how to migrate to a source mailing label

[maravento]

When migrating IMAP zimbra to IMAP gmail, the migration does not create a label in gmail from the source email, but sends the migration to the mailbox, mixing it with the other existing emails (it only creates labels that do not exist in gmail).

How can I migrate to a label with the name of the source mail?

For example:
label: [email protected]
sublabels: comments, send, etc...
