Issue Summary

Jira migrations may fail due to invalid references in JQL filters associated with boards. One such examples is caused by https://jira.atlassian.com/browse/JSWSERVER-15353 

One example of this is a deleted version:

2020-04-30 22:36:07.910 ERROR CCMP project-import We couldn't import Board 'CCM Product Team board'. Reason: query: The value '2.2' does not exist for the field 'fixversion'.. This caused 904 other items to fail.

Steps to Reproduce

1. Create a Jira Software Project
2. Create a version and associate some issues with it
3. Create a filter using this version and associate it with a Project Board
4. Delete the version
5. Try to migrate this board

Expected Results

JCMA handles the invalid reference in a better way, perhaps allowing the admin to edit the filter on the fly before migrating.

Actual Results

The migrartion fails:

2020-04-30 22:36:07.910 ERROR CCMP project-import We couldn't import Board 'CCM Product Team board'. Reason: query: The value '2.2' does not exist for the field 'fixversion'.. This caused 904 other items to fail.

Workaround

Manually ensure the board and filter is valid before migrating.
