Upgrade notes from Bamboo 4.4 to 5.0

To upgrade to Bamboo 5.0, follow the instructions in the Bamboo upgrade guide.

We strongly recommend that you back up your Bamboo instance and database before upgrading, as described in the Bamboo upgrade guide.

'buildnumber.txt' generation has been removed and replaced by an optional plugin

The 'buildnumber.txt' file is no no longer automatically generated in the working directory. If you rely on this funtionality, then you must install the the Build Number Stamper plugin from the Atlassian Marketplace.

No agent upgrade required

In Bamboo 3.2, agents were changed so that no upgrade of agents are required. When Bamboo is upgraded, agents will automatically restart and update their executables from the server.

Sonar tasks plugin 1.7.0 may cause some UI problems

Sonar tasks plugin 1.7.0 may cause some parts the UI to display incorrectly display but does not cause any functional issues. This problem has been reported to the plugin vendor.

Upgrading from Bamboo prior to 4.1

In addition to the notes below, please read the Upgrade Guide for every version you are skipping during the upgrade. 

Notes for upgrading from Bamboo 4.0

• Bamboo's deprecated Remote API has been removed. If you are using this API, migrate to the Bamboo REST API.
• There are no major schema upgrade tasks that may cause the Bamboo upgrade from 3.4 to 4.0 to take an extended amount of time.
• If you are using Elastic Bamboo, we've upgraded JDK6, Grails 1.2, Grails 1.3 and Maven 3 to the latest minor releases on the stock images. Additionally, we've added Grails 2.0 to the image. See here for a complete list of elastic image contents.

Notes for upgrading from Bamboo 3.2

• If you are using Bamboo with Crowd, follow the instructions in Upgrading Bamboo with Crowd to Bamboo 3.2.
• If you've been using Amazon EC2 images with you custom EBS, see Updating EBSes created for Fedora to support Amazon Linux
• If you've customized Amazon EC2 images to work with Bamboo, see Creating a custom elastic image.

Notes for upgrading from a version of Bamboo prior to 2.7.4

• You will need to upgrade to Bamboo 2.7.4 before upgrading to Bamboo 4.3. If you are using a version of Bamboo earlier than 2.6.3, we recommend that you upgrade to 2.6.3 before upgrading to Bamboo 2.7.4. Bamboo 2.6.3 can be downloaded from the Bamboo Archived Downloads page. Bamboo 2.7.x introduces a number of significant and irreversible changes, so a phased upgrade is recommended. Please see the Bamboo 2.7.x Upgrade Guide for more details.
• You will need to set aside time, as described in the Bamboo 2.7.x Upgrade Guide, for Bamboo to migrate existing Plans to the new Plan structure in Bamboo 2.7.4.
• If you are upgrading from Bamboo 2.5 or earlier, you will need to set aside time, as described in the Bamboo 2.6 Upgrade Guide for Bamboo to migrate its test result data (stored in XML files on the filesystem) into the database.
• If you are upgrading from a version of Bamboo prior to 2.0, you must upgrade to Bamboo 2.0.6 first before upgrading to Bamboo 2.6.3 ( and then 2.7.4). Please read the Bamboo 2.0 Upgrade Guide for important upgrade instructions for upgrading from earlier versions of Bamboo.
