Unable to Find Server ID for Confluence 2.5.4 or Before
The upgrade process requires that a Server ID be entered from my.atlassian.com. There is no Server ID present from
Administration > License Details in Confluence.
Server IDs were not implemented until version 2.5.5.
Please contact our sales team to request a server ID.
Note that for evaluation licenses, the Server ID is required. You can get this from the License Details screen or the Setup Wizard.
