How to change a customer's party type

I often see customers that are created wrong in client's systems.  They will have a party type of "organization" when they should really have "person" or vice versa.  The difference between the two, as far as I can tell, is that organizations are permitted to have multiple contacts, and other little things like that, while person types are supposed to be simpler.

Here is a little static method I wrote to change their party type.  One thing to worry about, when you go from Organization to Person, you may want to check if there are multiple contacts before you make the change.  Not exactly sure what it will do.

static server boolean changeCustPartyType(CustTable _custTable, DirPartyType _dirPartyType)
{
    CustTable       custTable;
    ;

    if (_custTable && _custTable.PartyType != _dirPartyType)
    {
        ttsbegin;

        custTable.selectForUpdate(true);
        custTable.data(_custTable);

        custTable.PartyType = _dirPartyType;

        custTable.setNameAlias();

        DirParty::updatePartyFromCommon(custTable.PartyId, custTable, DirSystemPrivacyGroupType::Public, true);

        custTable.doUpdate();

        smmBusRelTable::updateFromCustTableSFA2(custTable);

        custTable.setAccountOnVend(custTable.orig());

        smmTransLog::initTrans(custTable, smmLogAction::update);

        ttscommit;

        return true;
    }

    return false;
}
