We are thinking of moving all our bugtracking tools to the atlassian suite. I am currently playing around with importing our bugdatabse ( bugtracker.net) to Jira. We have around 17000 bugs (including closed and opened bugs) and we wish to convert the complete worklog of the bugs (original creation date for bugs and comments, status changes, original author). I have tries using the both the REST and the SOAP interface to populate a Jira issue with all those info, but it seems that a lot of them are read only.
Am I doing something wrong or is there a way to import our database easily keeping all those informations?
