Planning to merge jira software 6.3.12 with jira software 7.13.5, whats the path?

We want to merge the two instances to have a single instance.

Hi @Venkata Guntuku 

Please go through the following link for complete details to merge two Jira Server instances: https://confluence.atlassian.com/jirakb/merge-multiple-instances-of-jira-server-244352137.html

In short:

If you want to merge JIRA A into existing JIRA B instance,

• Upgrade JIRA A to JIRA B's version
• Do XML backup for upgraded JIRA A
• Import XML into existing JIRA B instance.

Just to add this info as head's up.

If you plan to upgrade from JIRA and JIRA Agile less than 6.4.x and 6.3.5 respectively, you must upgrade to JIRA Software 7.0 as an interim version before upgrading further.

Good luck!
