Upgrading Bamboo from version 3.2 to version 4.0 or 4.0.1 fails on upgrade task 2707 with the following error:

  1. Sometimes just restarting Bamboo and letting that upgrade task run again can solve this problem.
  2. This issue is identified and fixed in a later Bamboo versions - 4.x. 
  3. Bamboo version 3.2 is EOL since August 2013, so there won't be any point release for this issue.
  4. The last resort is to upgrade to another version in between 3.2 and 4.0 before upgrading to version 4.0 or 4.0.1.
