Convert Order to Quote and Load to Current Cart in Magento

magento-enterpriseordersquotesales

I can successfully convert convert an order into quote but I still couldn't load it into current cart. I tried several methods but to no avail. Here's the simplest one:

$_quote = Mage::getModel('sales/convert_order')->toQuote($order)->save();
$_quote = Mage::getModel('sales/quote')->load($_quote->getId());
$_quote->setIsActive(true)->save();

I was able to get the quote ID but the quote object doesn't load to the current cart.

I also tried

$_quote = Mage::getModel('sales/convert_order')->toQuote($order)->save();
$_quote = Mage::getModel('sales/quote')->load($_quote->getId());

if ($_checkoutQuote->getId() != $_quote->getId() && $_quote->getId()) {
    $_checkoutQuote->merge($_quote)->save();
    Mage::getModel('checkout/session')
                    ->setQuote($_checkoutQuote)
                    ->init();
    Mage::getSingleton('checkout/session')->getQuote()->setIsActive(true)->save();
}

and similar approaches but still not loading the quote.
Thank you very much!

Please use the below code. It will may help you.

Mage::getSingleton('checkout/session')->setQuoteId($_quote->getId());

Code convert an order to quote please used below:

   $quote = Mage::getModel('sales/quote')->load($order->getQuoteId());
    if ($quote->getId()) {
        $quote->setIsActive(1)
            //->setReservedOrderId(null)
            ->save();
        Mage::getSingleton('checkout/session')
            ->replaceQuote($quote);
           // ->unsLastRealOrderId();
    }

Here the process:

Get Current quote

$currenQuoteId=Mage::getSingleton('checkout/session')->getQuoteId();

Convert Order to quote

$OrderQuote = Mage::getModel('sales/quote')->load($order->getQuoteId());

Active Quote

if ($OrderQuote>getId()) {
    $OrderQuote>setIsActive(1)
        //->setReservedOrderId(null)
        ->save();
}

Merge your current quote and order reverse Quote

if ($OrderQuote->getId() && $currenQuoteId != $OrderQuote->getId()) {
    if ($currenQuoteId) {
    $OrderQuote->merge(Mage::getSingleton('checkout/session')->getQuote())
        ->collectTotals()
        ->save();
    }

set quote to checkout session 

Mage::getSingleton('checkout/session')->setQuoteId($OrderQuote->getId());

 if (Mage::getSingleton('checkout/session')->_quote) {
            Mage::getSingleton('checkout/session')->delete();
        }
       Mage::getSingleton('checkout/session') = $OrderQuote;
    } else {
        Mage::getSingleton('checkout/session')->getQuote()->getBillingAddress();
        Mage::getSingleton('checkout/session')->getQuote()->getShippingAddress();
        Mage::getSingleton('checkout/session')->getQuote()->setCustomer(Mage::getSingleton('customer/session')->getCustomer())
            ->setTotalsCollectedFlag(false)
            ->collectTotals()
            ->save();
    }
