Hello Angela,
one should be able to "dump" the Informix portion of a Synergy Repository (only the meta-data that is) via "ccmdb dump <database_path> -to <dump_filename>" command.
After that command finished, you can most definitely "access" the <dump_filename>, but I am not sure how good that data format of the dump file can be processed on your end.
Keep in mind that Informix only holds the Meta-data of your repository data .. the second part would be your file system portion to form a complete image of your Synergy repository.
Hope that info helps somewhat ;)
