Class RemovePluginLicenseStoragePluginUpgradeTask

  • All Implemented Interfaces:
    BackupSupport, DatabaseUpgradeTask, UpgradeTask, UpgradeTaskInfo, org.springframework.beans.factory.Aware, org.springframework.beans.factory.BeanNameAware
    public class RemovePluginLicenseStoragePluginUpgradeTask
extends AbstractUpgradeTask
implements DatabaseUpgradeTask
    Upgrade task to remove the UPM Plugin License Storage Plugin from existing Confluence instances. Since 6.0 the Plugin License Storage Plugin is no longer bundled, so we need to remove any upgraded versions. This upgrade task will need to exist whilst we support upgrading from those versions.
    Since:
    6.2.4

    • Method Detail

      • runOnSpaceImport

        public boolean runOnSpaceImport()
        Description copied from interface: BackupSupport
        Returns true if an older Space can't be imported in a new instance without running this task. For example:
        • A task updating macro names in the BodyContent table would be blocking.
        • Tasks which updates data related to the space would be blocking.
        • A task upgrading the user table wouldn't be blocking.
        • Adding a mandatory column on space-related content breaks space import

        Note that tasks don't run on space import yet, so we just reject the import in this case.

      • breaksBackwardCompatibility

        public boolean breaksBackwardCompatibility()
        Description copied from interface: BackupSupport
        Returns true if a new export can't be imported in an older instance.

        Breaking compatibility means a snapshot of the new version will not work at all with the previous version. For example:

        • A destructive operation (Some data is replaced by another) breaks backwards compatibility
        • Adding a optional column does NOT break backwards compatibility
        • Data is copied to another column doesn't breaks backwards compatibility
        • A build number incrementation doesn't breaks backwards compatibility
        The best way to test is whether a newer export can be imported (with fully working features) in an older instance.
