Copy the <authorizer>...</authorizer> configured in the existing NiFi to new the NiFi file.

將在現有NiFi中配置的<authorizer> ... </ authorizer>複製到新的NiFi檔案。

If you are using the default “file-provider” authorizer, ensure that you copy the users.xml and authorizations.xml files from the existing to the new NiFi.

如果使用預設的“檔案提供者”授權者，請確保將users.xml和authorizations.xml檔案從現有檔案複製到新的NiFi。

Configuration best practices recommend creating a separate location outside of the NiFi base directory for storing such configuration files. If you are storing these files in a separate directory, you do not need to move them. Instead, ensure that the new NiFi is pointing to the same files. For example: /opt/nifi/configuration-resources/

配置最佳做法建議在NiFi基本目錄之外建立一個單獨的位置，以儲存此類配置檔案。如果要將這些檔案儲存在單獨的目錄中，則無需移動它們。相反，請確保新的NiFi指向相同的檔案。例如：/opt/nifi/configuration-resources/

Update the values based on values from the existing NiFi file.

根據現有NiFi檔案中的值更新值。

Use the existing NiFi bootstrap.conf file to update properties in the new NiFi.

使用現有的NiFi bootstrap.conf檔案來更新新NiFi中的屬性。

If you added any custom logging modification to the existing NiFi, make those same changes to the new NiFi.

如果您對現有的NiFi新增了任何自定義日誌記錄修改，請對新的NiFi進行相同的更改。

If you used a provider value in the existing NiFi, copy the <provider>...</provider> configuration from the existing NiFi to this file in your new NiFi.

如果您在現有NiFi中使用了提供者值，請將<provider> ... </ provider>配置從現有NiFi複製到新NiFi中的該檔案。

Use the existing file to populate the same properties in the new NiFi nifi.properties file.

使用現有檔案在新的NiFi nifi.properties檔案中填充相同的屬性。

This file contains the majority of NiFi configuration settings, so ensure that you have copied the values correctly.

該檔案包含大多數NiFi配置設定，因此請確保您已正確複製了這些值。

If you followed NiFi best practices, the following properties should be pointing to external directories outside of the base NiFi installation path.

如果您遵循NiFi最佳做法，則以下屬性應指向基本NiFi安裝路徑之外的外部目錄。

If the below properties point to directories inside the NiFi base installation path, you must copy the target directories to the new NiFi. Stop your existing NiFi installation before you do this.

如果以下屬性指向NiFi基本安裝路徑內的目錄，則必須將目標目錄複製到新的NiFi。在執行此操作之前，請停止現有的NiFi安裝。

nifi.flow.configuration.file=

If you have retained the default value, (./conf/flow.xml.gz), copy flow.xml.gz from the existing to the new NiFi base install conf directory.

Alternately, you can copy to an external location and update the property value to point there.

如果保留了預設值（./conf/flow.xml.gz），請將flow.xml.gz從現有值複製到新的NiFi基本安裝conf目錄。

或者，您可以複製到外部位置並更新屬性值以指向該位置。

nifi.flow.configuration.archive.dir=

Same applies as above if you want to retain archived copies of the flow.xml.gz.

如果要保留flow.xml.gz的歸檔副本，則與上述相同。

nifi.database.directory=

Best practices recommends that you use an external location for each repository. Point the new NiFi at the same external database repository location.

最佳做法建議您為每個儲存庫使用外部位置。將新的NiFi指向相同的外部資料庫儲存庫位置。

nifi.flowfile.repository.directory=

Best practices recommends that you use an external location for each repository. Point the new NiFi at the same external flowfile repository location.

最佳做法建議您為每個儲存庫使用外部位置。將新的NiFi指向相同的外部資料庫儲存庫位置。

Warning: You may experience data loss if flowfile repositories are not accessible to the new NiFi.

警告：如果新NiFi無法訪問流檔案儲存庫，則可能會丟失資料。

nifi.content.repository.directory.default=

Best practices recommends that you use an external location for each repository. Point the new NiFi at the same external content repository location.

最佳做法建議您為每個儲存庫使用外部位置。將新的NiFi指向相同的外部內容儲存庫位置。

Your existing NiFi may have multiple content repos defined. Make sure the exact same property names are used and point to the appropriate matching content repo locations. For example:

您現有的NiFi可能定義了多個內容儲存庫。確保使用完全相同的屬性名稱，並指向適當的匹配內容儲存庫位置。例如：

nifi.content.repository.directory.content1=
nifi.content.repository.directory.content2=

Warning: You may experience data loss if content repositories are not accessible to new NiFi.

Warning: You may experience data loss may if property names are wrong or the property points to wrong content repository.

警告：如果新NiFi無法訪問內容儲存庫，則可能會丟失資料。

警告：如果屬性名稱錯誤或屬性指向錯誤的內容儲存庫，則可能會丟失資料。

nifi.provenance.repository.directory.default=

Best practices recommends that you use an external location for each repository. Point new NiFi at same external provenance repository location.

最佳做法建議您為每個儲存庫使用外部位置。將新的NiFi指向相同的外部來源儲存庫位置。

Your existing NiFi may have multiple provenance repos defined. Make sure exact same property names are used and point to appropriate matching provenance repo locations. For example:

nifi.provenance.repository.directory.provenance1=
nifi.provenance.repository.directory.provenance2=

Note: You may not be able to query old events if provenance repos are not moved correctly or properties are not updated correctly.

注意：如果出處回購未正確移動或屬性未正確更新，則您可能無法查詢舊事件。

For the “local-provider” value, verify the location of “state/local” directory.

對於“ local-provider”值，請驗證“ state / local”目錄的位置。

If you have retained the default location (./state/local), copy the complete directory tree to the new NiFi. The existing NiFi should be stopped if you are copying this directory because it may be constantly writing to this directory while running.

如果您保留了預設位置（./state/local），請將完整的目錄樹複製到新的NiFi。如果要複製該目錄，則應停止現有的NiFi，因為它在執行時可能會不斷寫入該目錄。

Configuration best practices recommend that you move the state to an external directory like/opt/nifi/configuration-resources/ to facilitate easier upgrading later.

配置最佳實踐建議您將狀態移動到外部目錄，例如/opt /nifi/configuration-resources/，以方便以後的升級。

For a NiFi cluster, the “cluster-provider” ZooKeeper “Connect String" should be using the same external ZooKeeper as the existing NiFi installation.

對於NiFi群集，“群集提供者” ZooKeeper“連線字串”應使用與現有NiFi安裝相同的外部ZooKeeper。

For a NiFi cluster, make sure the “cluster-provider” ZooKeeper "Root Node" matches exactly the value you used in the existing NiFi.

對於NiFi群集，請確保“群集提供者” ZooKeeper“根節點”與您在現有NiFi中使用的值完全匹配。

If you are also setting up a new external ZooKeeper, see the ZooKeeper Migrator section of the NiFi System Administrator’s Guide for instructions on how to move ZooKeeper information from one cluster to another and migrating ZooKeeper node ownership.

如果您還要設定新的外部ZooKeeper，請參閱《 NiFi系統管理員指南》中的ZooKeeper遷移器部分，以獲取有關如何將ZooKeeper資訊從一個群集移至另一個群集以及遷移ZooKeeper節點所有權的說明。
