# How to Determine XML Backup Confluence Version

#### Still need help?

The Atlassian Community is here for you.

In certain cases when there are a number of XML backups in the backups folder under your Confluence Home directory and you do not have any clue which XML backup is from the Confluence version that you are looking for. This informational guide is commonly used for Confluence migration purposes.

## Determining the XML backup Confluence version

1. Unzip Confluence XML backup.
2. Search and open the exportDescriptor.properties file in an editor.

3. The file contains information such as follows:

#Thu Jan 29 11:36:51 CET 2015
buildNumber=4517
ao.data.version.com.atlassian.mywork.mywork-confluence-host-plugin=2.2.7
ao.data.version.min.com.atlassian.confluence.plugins.confluence-space-ia=5.0
exportType=all
createdByBuildNumber=5638
backupAttachments=false
defaultUsersGroup=confluence-users
ao.data.list=com.atlassian.confluence.plugins.confluence-space-ia, com.atlassian.mywork.mywork-confluence-host-plugin
ao.data.version.min.com.atlassian.mywork.mywork-confluence-host-plugin=1.1.30
ao.data.version.com.atlassian.confluence.plugins.confluence-space-ia=8.3
4. Get the createdByBuildNumber information.
5. Compare the build number with Confluence Build Information documentation.

For example, the createdByBuildNumber parameter is 5638. Hence, it describes the Confluence version 5.6.5.
