As a build administrator I want to change the Bamboo build number to another number to preserve continuity of build numbers when migrating from other continuous integration systems.
Add a form field in build administration where the build number can be changed.
The build number can be reset by cloning the existing plan to create a replacement. The build number can be increased using a SQL query. The build number cannot be decreased due to conflicts with multiple tables that reference the past builds.
For complete details of the workarounds please see Unable to change the current build number in Bamboo
