Bamboo 1.0.4 Upgrade Guide
Upgrading from Bamboo 1.0.3 to 1.0.4
In this version, an upgrade task has been added to update Perforce plans to use the change list number rather than the timestamp when detecting changes. Please ensure that you have connectivity to the Perforce server before you upgrade.
If Bamboo encounters any errors during the upgrade task it will set the Perforce plan's last change list number to 0. This means that the next time you build that plan there may be some unusual results (eg. picking up every single change list). Once this build is complete normal behavior will resume.
It is strongly recommended that you back up your xml-data directory before proceeding. For full instructions please follow the Bamboo upgrade guide.
Upgrading from Bamboo 1.0.2 and earlier
In addition to the above, please read the Upgrade Guide for every version you are skipping during the upgrade. The complete list of Upgrade Guides is available here
