We are developing project on community edition but since community edition have a deadline, we have to move current developed project into a new application by using import wizard but when importing it shows me this error - Import cannot proceed due to exception: java.lang.UnsupportedOperationException: Unsupported archive type: 6.

Furthermore, this is the log file details according to this error:
