How can I migrate Jira data between 2 instances of different versions?

[RTD5033]

I have a requirement to move Jira data between 2 instances residing on different servers.  One instance is running on a REHL 6 server running Jira 7.1.9 connected to a MySQL 5.1 (Instance A).  Currently this instance is being utilized by our user group. 

The other instance is running on REHL 7, Jira 8.2.2 and MySQL 5.7 (Instance B).  

I need to maintain all server level configurations on instance B, but move all users, workflows, user stories etc from instance A to instance B.  

Is there some more ideal way to migrate this data between instances?  At the moment, have essentially tried everything I could find in the KB, with the exception of upgrading the older instance before attempting to migrate again.  (I have yet to do this because I would need to upgrade both the Jira instance and MySQL versions, as Jira 8.2.2 is not compatible with 5.1, and MySQL 5.7 does not run on REHL 6 without some massive headaches).

Hello @Arthur Goncalves, would the CSV file be generated automatically or manually created?
