import data problem.

This data appears to be from an older version of JIRA. Please upgrade the data and try again. The current version of JIRA is at build number '846', but the supplied backup file was for build number '6007'.

You cannot do Project imports using backup files from older versions. If you want to import a single project, the export has to be from the same version.

If not you can import the complete file which will overwrite the complete contents of the JIRA instance.
