How do I migrate from Identity Federation for AWS 1.x to Identity Federation for AWS (Jira) 2.x?

Unfortunately there is no upgrade path from Identity Federation for AWS 1.x to its successor Identity Federation for AWS (Jira) 2.x for technical reasons outside of our control. To ease the migration, you can start using versions 1.x and 2.x for Jira side by side, as they are entirely independent add-ons (usability flaws apply though) - please refer to https://utoolity.atlassian.net/wiki/spaces/UAAKB/pages/30900263 for details.
