Assisted migration process to enable all features with Organizations
If you are an Enterprise customer, it can be difficult to complete the standard migration process due to the large number of accounts you might manage. For example, you might have difficulty obtaining approval to migrate all invited accounts in large organizations.
Assisted migration help with this process by enabling customers with an Enterprise Support plan to request that AWS migrate their organization to all features on your behalf. This process requires that you sign an agreement contract affirming that you own all accounts, followed by a 14-day waiting period. This waiting period provides accounts time to leave the organization if the accounts want to before the migration to all features takes effect.
If you use assisted migration, you do not need to worry about accessing your invited account as the root user to accept the migration to all features.
You can reach out to your Technical Account Manager (TAM) for exact details, progress, and timelines for the assisted migration.
