We have a Bamboo Instance which uses the internal User Management System. We now want to migrate this to use Crowd but we are not sure what will happen to the existing user accounts which exist in the local bamaboo user directory.
We followed the convention of creating users in Bamboo using their windows AD usernames. These are also what Crowd uses in out crowd configuration. The end result is we'll have duplicate usernames in both crowd directories and in Bamboo's Internal user directory.
What is the best way to switch across to using Crowd without getting into the situation where duplicate usernames are causing access issues to Bamboo
