We are evaluating JIRA with bitbucket/stash. We are planning to use on-demand jira with bitbucket. Looks like it integrates well, so far. We want to keep this model for at least next 6-8 months. After than we plan to bring in things in-house behind firewall, so we may migrate towards getting downloadable version of JIRA and bitbucket, which I beleive Atlassion sells as stash. My questions are:
1) After we migrate from bitbucket to stash, would we still be able to keep the history of commits/branch, comments, etc?
2) If we migrate from ondemand Jira to downloaded version, do they provide migration path where we can keep the history of bugs/enhancement, etc and to downloaded verison.
3) Does linking of jira to git commits be transferred from ondemand version of Jira to downloaded version?
