Upgrade notes from Bamboo 5.2 to 5.3

Bamboo 5.3 includes features that protect you against XSRF attacks.

These features are potentially disruptive, but we encourage you to enable them early so that you can test compatibility of your scripts and plugins.

See Configuring XSRF protection to learn how to manage your XSRF attack protection.

For security reasons, Atlassian recommends enabling XSRF protection after upgrade. Disable it only if you find out that it prevents your workflows from working. If that happens, you will be able to disable XSRF protection without any consequences.

Is my Bamboo server already protected against XSRF attacks?

Upgrade notes from Bamboo 5.x to 5.3

Tomcat now replaces Jetty as the standalone app server since Bamboo version 5.1.0. This means that the way Bamboo is started, stopped and upgraded has changed. Also, the custom configurations done in the  <Bamboo installation directory>/conf/wrapper.conf should be transferred to  <Bamboo installation directory>/bin/ file (or <Bamboo installation directory>/bin/setenv.bat for Windows instances) as there is no wrapper.conf file in Bamboo server since version 5.1.0 (the wrapper still exists for the remote agents). For more information about how to configure some of the parameters that were set using the wrapper, please refer to - Configuring your system properties.

Please follow the below listed steps when upgrading to Bamboo from version 5.x to 5.3 (in addition to migrating the custom changes from the wrapper to

Upgrade notes from Bamboo from 4.1.x and later to 5.3

To upgrade to Bamboo 5.3 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 functionality, 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.

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

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.

Developing for Bamboo 5.3

If you are a Bamboo plugin developer, please refer to our Bamboo API Changes by Version guide, which outlines changes in Bamboo that may affect Bamboo plugins compiled for earlier versions of Bamboo.
