Both .cpf and .ct8 files come from CaseMap fact- and issue-management software from LexisNexis. We do not have any specific information about cpf to ct8 conversion, but it might be simply a matter of making new template based on existing file. In any case, if you have issues with the export of either files, it would be best to contact LexisNexis support.
