The tasks required to upgrade Jira manually will remain the same as those for the installer. Refer to the previous recipe for common tasks involved. As the installer automates many backup tasks while upgrading Jira manually, you will have to do the following:

1. Back up the Jira database with its native backup utility.
2. Back up the JIRA_INSTALL directory.
3. Back up the JIRA_HOME directory.
4. Get a list of all the customized files in the JIRA_INSTALL directory from the System Info page in Jira.
