We currently have 2 Jira v6.3-OD-07-013 online instances and I need to merge these into one instance. I have seen the steps for moving projects between instances but wanted to verify what is the best way / easiest way of achieving this.
I've tried to download a local version of Jira, but this is version 2.6.7 so the project import will not work as the versions are not the same. I'm able to import the first online instance from a backup, but then the project import function is no longer available to try and import the projects from the other instance.
Is there any way of achieving this?
