Mendix Update 5.19 to 6.10.1

hi all, Am trying to update my project from 5.19 to 6.10.1. Import mappings and export mapping which is created for consuming a client web service is throwing below. Let me know the steps to proceed further.  i need to update the entire mappings again from the start or is there any work around. Regards Thilagavathi

This error occurs at all your mappings or just one or two? And can you show the complete message. Is it maybe caused by any domain-model changes? Give us some screenshots on the mapping and the datamodel, maybe we can see some oddity causing the problem.

Otherwise recreating them from scratch will likely help, but I understand that that seems cumbersome and errorprone.
