How can I migration Jira Another Server

[Alper]

Hi!  Can we unite Jira 6.2.2 database which we are using at the moment with Jira 6.4.6 and tranfer?

Because, there are new screems, custom fields and new databases on the newly founded server new Jira 6.4.6 .  How can we transfer them to the old database by not being have to delete them?

Thank You

The best path is probably

1. Upgrade the 6.2.2 to 6.4.6
2. Copy the config you need from the upgraded 6.2.2 into the 6.4.6
3. Export the upgraded 6.2.2, then use project import to pull the issues you need into 6.4.6

There are some utilities on the marketplace that can help you with point 2
