  - MAXIMUM_CLOUD_BUILD_VERSION_NUMBER
```
protected static final int MAXIMUM_CLOUD_BUILD_VERSION_NUMBER
```
    In Confluence 8.0.0 we have removed upgrade tasks with build numbers lower than 7103 Cloud's build number is still that of the fork "6452", so our build number is too high. This temporary fix ensures the build number is what cloud expects until we update the logic regarding cloud server compatibility.

  - configuredBuildNumberNewerThan
```
public boolean configuredBuildNumberNewerThan(String buildNumber)
```
    Description copied from interface: UpgradeManager
    
    Returns true if the passed build number is less than the configured build number - that is, the version of the currently running Confluence is newer than the version passed.
    
    Specified by:
    
    configuredBuildNumberNewerThan in interface UpgradeManager
  - taskNewerThan
```
public boolean taskNewerThan(String buildNumber,
                             UpgradeTask upgradeTask)
```
    Description copied from interface: UpgradeManager
    
    Returns true if the build number for the task is greater than the passed build number. Usually indicates that the task should run as part of an upgrade.
    
    Specified by:
    
    taskNewerThan in interface UpgradeManager
  - initialUpgradeFinished
```
protected void initialUpgradeFinished()
                               throws Exception
```
    Once all upgrade tasks have been completed without error, make sure the build number stored in the applications main configuration file and database now matches the build number of this version of the release.
    Note that this method is called "initialUpgradeFinished" because any deferred pluginDependentUpgradeTasks may still have to run, so the upgrade process is not yet complete.
    
    Throws:
    
    Exception - when setting the database or configuration build number fails
  - entireUpgradeFinished
```
public void entireUpgradeFinished()
```
    Description copied from interface: UpgradeManager
    
    Called when all immediate and deferred upgrade actions have been performed *if* an upgrade was needed.
    
    Specified by:
    
    entireUpgradeFinished in interface UpgradeManager
  - getRealBuildNumber
```
protected abstract String getRealBuildNumber()
```
    Returns:
    
    The build number of the new version of Confluence being upgraded to. This number can be found in the default.properties of the new expanded WAR
  - getDatabaseBuildNumber
```
protected abstract String getDatabaseBuildNumber()
```
    Returns:
    
    The build number of the data in the database. If the version of the database data can not be determined, this method should return the same value as getConfiguredBuildNumber().
  - setDatabaseBuildNumber
```
protected abstract void setDatabaseBuildNumber(String databaseBuildNumber)
                                        throws Exception
```
    Once the upgrade is complete, we'll need to set the new database build number in the database.
    
    Parameters:
    
    databaseBuildNumber - The new database build number
    
    Throws:
    
    Exception - when there is any problem setting the database build number
  - permitDatabaseUpgrades
```
protected boolean permitDatabaseUpgrades()
                                  throws UpgradeException
```
    This is used to guard against database upgrades being performed multiple times on the same database. By default, assume a non-clustered setup and allow database upgrades.
    
    Returns:
    
    True by default. Is overridden for cluster upgrades.
    
    Throws:
    
    UpgradeException - If the implementation of this method encounters any errors.
  - beforeUpgrade
```
protected void beforeUpgrade()
                      throws UpgradeException
```
    Throws:
    
    UpgradeException
  - postUpgrade
```
protected void postUpgrade()
```
  - isUpgraded
```
public boolean isUpgraded()
```
    Specified by:
    
    isUpgraded in interface UpgradeManager
    
    Returns:
    
    true if the UpgradeManager was able to successfully upgrade this instance, or if no upgrade was necessary; otherwise false.
  - getOldestSpaceImportAllowed
```
public String getOldestSpaceImportAllowed()
```
    Description copied from interface: UpgradeManager
    
    Calculates the oldest build number from which a space can be imported.
    
    Specified by:
    
    getOldestSpaceImportAllowed in interface UpgradeManager
    
    Returns:
    
    the build number
  - getExportBuildNumber
```
public String getExportBuildNumber(boolean isSpaceExport)
```
    Description copied from interface: UpgradeManager
    
    Tells the earliest version the exports will be compatible with.
    
    Specified by:
    
    getExportBuildNumber in interface UpgradeManager
    
    Parameters:
    
    isSpaceExport - true if the export is about a space, false for a global export.
    
    Returns:
    
    a build number
  - getPluginExportCompatibility
```
public Map<String,PluginExportCompatibility> getPluginExportCompatibility(boolean isSpaceExport)
```
    Description copied from interface: UpgradeManager
    
    Returns the list of plugins with data (especially plugins with Active Objects data) and tells how backward-compatible they are.
    
    If at least one plugin isn't compatible, the importer silently doesn't import any data.
    
    What is a compatible version?
    
    The data is exported as-is in XML and reimported in an earlier version. If the earlier version of the plugin is able to read the data without fault, then it is compatible. Note that there is no downgrade task, obviously.
    
    Specified by:
    
    getPluginExportCompatibility in interface UpgradeManager
    
    Parameters:
    
    isSpaceExport - true if the export is about a space, false for a global export.
    
    Returns:
    
    a matrix of plugin key and minimum versions of the plugins.
