Project Migration from Jira 3.10 to Jira 6.4.9

[Sachin Dhamale]

I want to migrate project data from JIRA v3.10 to JIRA v6.4.9.

In that JIRA v3.10 i have test steps and expected result.

so i want to know what is best way to migrate? should i first upgrade JIRA from 3.10 to 6.4.9 but it will take so much time because i have to go step by step means first need to upgrade to 4 , 5 then 6

Or Should i migrate issue using CSV import? but int that how do i move the attachment and test steps and expected result.

You'll need to upgrade all the way to 6.4 if you want to use "project import".  That can import a whole project, with all the core data (not add-on data, but the issues, history, fields and the rest).  It does need you to have configured the target project first though.

Hi Sachin,

If you are going to export to csv you will lose a lot of information (comments, update information, etc, ... )

So i would upgrade JIRA if i where you.

Even if it means you have to repeat the process a few times. 

According to https://confluence.atlassian.com/jira/upgrading-jira-3-x-data-to-jira-6-x-251004540.html

you only need to upgrade to 4.4.5 first.
