Description
Issue Summary
Project import using XML back-up fails abruptly, and the UI complains,
"The import was aborted because there were too many errors. Some errors are listed below. For full details about the errors please see your logs. Please note that some elements have been created. You want to consult your logs to see what caused the errors, delete the project, and perform the import again"
In the server logs, it is failing with NullPointerException at com.atlassian.jira.imports.project.customfield.VersionCustomFieldImporter.getMappedImportValue(VersionCustomFieldImporter.java:29).
Notes:
- This doesn't usually happen when the source and destination are the same
- Though the error happens, it imports many of the issues from the selected XML backup and this is failing after project re-indexing. This causes ambiguity in data(users will see issues imported but some fields might be missing, some fields will not have proper values)
This is reproducible on Data Center: (yes)
Steps to Reproduce
This issue happens under two conditions(as of now identified)
- There are issues in the XML backup with a value in the version custom field that was pointing to a non-existing project version.
- There are issues in the XML backup with version custom field values that doesn't have the context existing(like the issue type has been removed from the field context or the project doesn't exist in the context).
Expected Results
Project import should validate this before import and proceed
Actual Results
The below exception is thrown in the xxxxxxx.log file:

Workaround
- First thing is to make sure that the version type fields are having proper context on both source and target(issue type and projects are selected if it is not set to global)
- Run the below SQL to find zombie version values and remove/update them and regenerate the XML back-up
SELECT jiraissue.id as issue_id, jiraissue.issuetype, project.id as project_id, customfield.id as custom_field_id, customfield.cfname, customfieldvalue.numbervalue FROM jiraissue JOIN customfieldvalue ON customfieldvalue.issue = jiraissue.id JOIN customfield ON customfield.id = customfieldvalue.customfield JOIN project ON project.id = jiraissue.project WHERE project.pkey = 'XYZ-PROJ' AND customfield.customfieldtypekey = 'com.atlassian.jira.plugin.system.customfieldtypes:version' AND customfieldvalue.numbervalue NOT IN (SELECT id from projectversion WHERE projectversion.project = project.id);
