I am migrating through Webservice the data of customers from one Magento 1.7 to another that has 1.9.3
The case is that with magento 1.9.3 I can connect without problems, but if I do with the older version, 1.7, it gives me an error.
Fault string: looks like we got in XML document
Curiously the two magentos are on the same server, with the same sql, same php and same configurations, but I do not know where the problem may be, and I can not get the list of clients.
I will appreciate any comments that may give me a clue to find the problem.
Thank you very much.
