Can I assign two roles for two group with same role name ??

[arifh]

In D7 I can add two role for two group with same name. Because two role rid is different.
Example -> Group A --> Subadmin (Rid --> 50)
Group B --> Subadmin (Rid --> 51)

But In D8
$entity_type = 'node';
$entity_bundle = '<bundle name'>;
$group_id = 'unique gid';
$extra_role_1 = OgRole::create();
$res = $extra_role_1
->setName('name')
->setLabel('lable')
->setGroupType($entity_type)
->setGroupBundle($entity_bundle)
->set('group_id',$group_id)
->save();

Here "name" behave as a unique rid. We can't use same multiple time.
Here "name" store at Config table like "og.og_role.node-bundle-subadmin"
Only lable can repeat.

When I migrate my feature D7 to D8, how can I migrate those D7 role with IDs
