Migrated issue, originally created by Christian Theune (@ctheune)

Hi!

I'm currently upgrading from an older version where I used the following code when stamp() did not exist yet:

migration_context._update_current_rev(
migration_context.get_current_revision(), script.get_current_head())

This code was fine to call directly after create_all() and the new documentation says that one should use command.stamp. In my situation I do not have a manifested config file to use the Configuration object with and I think I should be able to just call

migration_context.stamp(script, "head")

This fails for new databases because the initial version table does not get created. I see that the MigrationContext class has _ensure_version_table() which is used except in stamp(). This looks like an accident to me.
