    • 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.

      Specified by:
      runOnSpaceImport in interface BackupSupport

    • 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.

    • getBuildNumber

      public String getBuildNumber()
      Specified by:
      getBuildNumber in interface UpgradeTaskInfo
      Overrides:
      getBuildNumber in class AbstractUpgradeTask
      Returns:
      The build number that this upgrade is applicable to

      public void doUpgrade() throws Exception
