I try to import my existing customers to the new site which is prepared using prestashop. I prepared the cvs file as in the samples.I have over 17000 existing customer records. When I tried to import whole file I managed to insert around 5000 records. I thought that maybe this number is too high for prestashop it causes some memory problems. Later I divided original file into smaller files which have 5000 records at most than I could import around 1500 records :) Later I tried file with 1000 records result was even smaller.
In the end I tried file with 200 records at most and I could import around 87 using cvsimport. This is meaningless. Everytime I clear the table before cvsimport... I don't get an error. It looks like import finishes correctly but when I check the # of records I see the bad result....
Is this a known issue? How can I solve this ?
