JIRA migration: BugZilla multi-line desc/comments

BugZilla MySQL database

The longtext table contains each bug_id's associated multi-line desc and multi-line comments.

MySQL query to get bug_id and the text result

SELECT 

    bug_id
    , thetext
FROM
    bugs.longdescs as T1
where
    T1.bug_id in (SELECT 
           bug_id
        FROM
            bugs.bugs
        where
            product_id in (SELECT 
                    id
                FROM
                    bugs.products
                where
                    (name like 'MY_BUGZILLA_PROJECT')))
Order by T1.bug_id
For each of bug_ids associated multi-line thetext entries: 
First entry is the bug_id associated desc
Remaining entries (if existed) are the bug_id associated comments.

Migrate BugZilla multi-line desc & comments into JIRA

1. create a BugZilla query for JIRA migration without multi-line desc/comments
2. JIRA, Administration -> System -> Import & Export -> Import External projects -> CSV Import
3. create a MySQL query to only contains bug ids, and save the query result as XML format

SELECT 
    bug_id
FROM
    bugs.bugs
where
    product_id in (SELECT 
            id
        FROM
            bugs.products
        where
            (name like ' MY_BUGZILLA_PROJECT ')))
Order by bug_id
4. run a PERL script (i.e. xmlBugIdExportIntoJIRA.pl) through JIRA cli interface updating desc/comments on Linux platform from where BugZilla's desc/comments UTF-8 code issue will be solved)
