No, you are not allowed to transfer products.

In order to transfer assets, pension assets (investment products held) are converted into cash.
Therefore, even if the products with the same name are offered both in our iDeCo and your previous company, the products will be automatically sold and converted into cash during the rollover procedures.
The purchase will be made after the completion of the rollover to an individual-type DC (iDeCo) at Sompo Japan DC Securities.
