Several warnings in migration 4.4 to 5.0

Hi Devs
when I try to migrate a database from 4.4 to 5.0 version, I get these warnings:

trytond-admin …

WARNING trytond.convert Field symbol of 147@currency.currency not updated (id: cop), because it has changed since the last update

WARNING trytond.convert Field icon of 156@ir.ui.menu not updated (id: menu_banking), because it has changed since the last update

WARNING trytond.convert Could not delete id 7 of model account.journal.type because model no longer exists.
INFO trytond.convert Deleting 8@account.journal.type from account_statement.journal_type_statement
I have follow migration topic and the migration process is successful I can to enter to DB, but this warnings persists, How do I remove them?

You can go to “Administration > Models > Models > Data” and synchronize those that are out of sync.
Beware of Issue 7950: Data synchronised always out of sync - Tryton issue tracker which prevents to synchronize some cases.
