Merge user content ownership

[Dominik Blum]

Is there any knowledge base article that describes how to merge content of users from different active directories for crucible/fisheye?

For confluence and jira there are articles for that purpose:

For jira and confluence the migration went pretty smooth but for crucible I tried to create all database queries on my own. I tested the queries on a single user (or better to say two users. One from the old and one from the new user repository) and now none of them can see the content that was created by the user from the old user directory. The reviews now are assigned to another user, that was not affected by my queries.

So far I did not reindex the database as we have arround 100k revisions what can take days or weeks if you believe other people's post here in the community.

Is there a knowledge base article about this process in crucible? Went anybody of you through the same process? Are there better options as changing the user mapping in confluence.
