Changing multiple account ownership to root

[dxer]

I am trying to change back account ownership of a reseller to ROOT. But when I remove reseller privilegues, ownership of accounts stays with this reseller.
I tried to use option to change multiple account ownership within reseller center but there is no "root" under owners to change too.

Any ideas how to do this ?

You can change ownerships in WHM/List Accounts end column - Reseller, click on the small edit icon and you will be presented with a Change Ownership list box.

I know that, but I need multiple option because I have like 150 accounts to convert to root ownership

You could manually edit the needed accounts files in /var/cpanel/users/ with a text editor that has search/replace capability.
