Do you have a lot of profiles? I had the same issue on one of my clients site, and simply resumed migration, and it resumed where it left off

Hello thanks

yes 13,500 profiles only one profile was imported.

now i get a "page not found" on all of my profile views on my 6.1 site.. damn

i solved the 404, i still cant import profiles to 7.0

The process of data transfer takes a lot of resources. before moving try to maximize the power of mysql server (using directives in my.cnf), as well as to increase the memory for php
