[Users] quota file not compatible between OpenVZ 32 and 64 bits

Thanks for your answer Alexander.
As you explain it, it's like you upgrade to 64bits without a new 
installation. Is that possible? Our intention is to make a new 64 bit 
installation on one of our cluster nodes, move VEs there step by step, 
and at last do the same with the remaining one.
