We are migrating from Jira server with MS Active Directory to Jira cloud. Our organisation AD has 100s of users and 98 of them fail validation in the migration tool. There are less than 10 jira users that we want to migrate and map to their existing atlassian accounts (we use bitbucket cloud) - the email addresses on the AD account match those on their existing atlassian accounts.
I am unable to manually create internal directory accounts in Jira server with usernames that match those in AD - prevents me with a validation message about the username already existing.
Could i update the directory id in the cwd_user table from the AD to internal directory and then perform a migration?
