Migrate from teams to groups with Terraform

Teams in Aiven are becoming groups. Groups are an easier way to control access to your organization's projects and services for a group of users.

To get started using organization groups, replace your existing teams with groups.

For each team, make a note of:
- which users are members of the team
- which projects the team is assigned to
- the team's role for each project
To use the resources related to groups, set the PROVIDER_AIVEN_ENABLE_BETA environment variable to true.
For each team in your organization, create a group with the same name. The following sample creates a group using the aiven_organization_user_group resource.
```
resource "aiven_organization_user_group" "admin" {
  organization_id = data.aiven_organization.ORGANIZATION_RESOURCE_NAME.id
  name       = "Admin user group"
  description = "Administrators"
}
```
note
Users on the Account Owners team automatically become super admin with full access to manage the organization. You don't need to create a group for these users or manage this team after the migration.

To add the users to the groups, use the aiven_organization_user_group_member resource:

resource "aiven_organization_user_group_member" "admin_members" {
  group_id      = aiven_organization_user_group.admin.group_id
  organization_id = data.aiven_organization.ORGANIZATION_RESOURCE_NAME.id
  user_id = "USER_ID"
}

To add each new group to the same projects that the teams are assigned to, use the aiven_organization_group_project resource:

resource "aiven_organization_group_project" "admin_project1" {
  group_id      = aiven_organization_user_group.admin.group_id
  project = aiven_project.PROJECT_RESOURCE_NAME.project
  role    = "admin"
}

After confirming all users have the correct access, delete the team resources.
