Moving Jira/Confluence with different username mappings

[Eugene Kim]

Greetings,

My team is moving our Jira projects and Confluence spaces out of a corporate-wide Atlassian Cloud instance into our own Atlassian Cloud instance.  All the people have accounts on both the old and the new instances, with a few caveats:

1. Their email is different (john.doe@xyz.com versus john.doe@xyz.io); and
2. For some users, their Atlassian username is also different (john versus john.doe, for example).

How can I migrate the projects/spaces preserving the right ownership mapping, e.g. so that the Atlassian username john in the old instance becomes the Atlassian username john.doe in the new instance?

I understand the last resort is to hand-fix or maybe use an API to search for and replace the old username with the new ones, but 1) I want to avoid having to do this, having 100+ users, and 2) I need all the places where the username may appear so that I can search the right places/fields.

I am hoping we won't have to resort to the last resort.

Please review: How to merge two different JIRA Cloud applications together.

We have a request open to make the process easier: Ability to merge Atlassian accounts to a single account with secondary emails It's on a public facing Jira issue tracker in case you would like to communicate directly with the development team.
