And since it looks like anonymous reads are not allowed for Atlassian's OnDemand support system, for the record, here is the title/description I used for the issue:
Title: Migrating from Apache Spark project's OnDemand JIRA to the apache.org hosted JIRA
I'm a contributor to the open source Apache Spark project, and we are trying to migrate from the onDemand JIRA for Spark hosted by Atlassian (spark-project.atlassian.net) to the version of JIRA hosted by Apache for their projects (https://issues.apache.org/jira
We are having some issues because the versions of the two don't seem to be compatible for the export-then-import we need to perform.
You can see what steps we've taken in this issue https://issues.apache.org/jira/browse/INFRA-6419
Specifically, the existing Spark OnDemand Jira is now at JIRA v6.2-OD-03 and the Apache version is 6.1.
We have about 1000 issues now so it would be very expensive to either lose or have to manually copy over all issues.
Would you be able to assist us in exporting a version of our OnDemand JIRA that can successfully be imported to the JIRA hosted by the Apache Foundation? Perhaps it would be enough to just change the version number in the exported file and try to import it, or are the changes between these two versions significant enough that this would fail (or worse)?
Thanks a ton in advance!
