Method Detail

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

runOnSpaceImport

public boolean runOnSpaceImport()
Description copied from interface: BackupSupport

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

Specified by:

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: The best way to test is whether a newer export can be imported (with fully working features) in an older instance.

Specified by:
breaksBackwardCompatibility in interface BackupSupport

getShortDescription

Description copied from interface: UpgradeTaskInfo
A short (<50 chars) description of the upgrade action
