The provider has two resellers in OBAS, and the resellers have their own customers with subscriptions.
The provider wants to move the accounts with all their subscriptions from one reseller to another one.
Another use case - The provider wants to move accounts with all their subscriptions from some reseller directly to the provider account. Or vice-versa, move the account from the provider to some reseller.
Such behavior was implemented since OBAS 4.5.7.
To resolve the issue, please upgrade to 4.5.7 as described in How to upgrade OBAS system to the latest available version.
