I've run help mand on sequelize and saw that there are two different mands with the same description:

$ sequelize help:migration:create

Sequelize [Node: 6.9.5, CLI: 2.5.1, ORM: 3.8.0, mysql: 2.5.0]

Loaded configuration file "config\config.json".
Using environment "development".
COMMANDS
    sequelize migration:create   -- Generates a new migration file.
    sequelize migration:generate -- Generates a new migration file.

Is there any difference between them?

No difference: migration:generate is alias for migration:create

https://github./sequelize/cli/blob/master/lib/tasks/migration.js#L20

There is a small difference between create and generate:

1. Create: This will create migration files that will have empty up and down query objects, in which you can write down your queries to update the database.
2. Generate: This will generate the migrations with up and down queries by observing your database changes. You can see more of migration on the official sites.
