Import from Bugzilla: combine multiple fields into a custom field

[Ori Gabai]

We're in the process of migrating from Bugzilla to JIRA.

When opening issues, we specify the build in which the issue was found in a custom "Build Number" field. We have multiple projects defined in Bugzilla, and unfortunately each of these has its own separate "Build Number" field.

Right now, when I import, I get 3 separate fields, each named "Build Number." What I want to do is combine all the separate build fields from Bugzilla into a single field in JIRA (for any given imported issue, only one of the build fields in Bugzilla has a value), while importing them. Is this possible?

If the above is not possible, is it possible to effect this change via bulk edit of issues somehow?

JIRA Command Line Interface might help you, at least to fix a few things like this up after the import.
