Upgrading ThingsBoard PE to 3.0.1

NOTE: These upgrade steps are applicable for ThingsBoard version 3.0PE. In order to upgrade to 3.0.1PE you need to upgrade to 3.0PE first.

升级至 ThingsBoard 3.0 前的重要提示

ThingsBoard UI 已从 AngularJS 1.5.8 重写为 Angular 9。
- 这意味着什么？
  - 概括而言，意味着：现代化应用、更易开发前端元素、性能提升以及 UI 定制更灵活。
- 如何升级？
  - 若您不在仪表盘中使用自定义部件或自定义操作，可安全升级。
  - 新的 JS 框架可能不完全支持您当前的代码（自定义部件和自定义操作），需稍作重构。因此建议您使用我们的云环境或开发实例测试您的定制内容。
从纯 Cassandra 迁移至混合数据库方案
- 我们仍支持 Cassandra 存储遥测数据，但不再用于存储设备、客户、租户等实体。
- 这意味着什么？
  - 这将简化维护和未来改进，并将在 v3.1 中支持高级搜索能力。
- 如何升级？
  - 若您使用纯 PostgreSQL 或 PostgreSQL（实体）+ Cassandra（遥测），则不受影响。
  - 若您使用纯 Cassandra，升级过程将自动执行但需一定时间。停机时间取决于设备、属性、告警和关系的数量。若上述实体少于 1000 万，升级通常仅需数分钟，具体取决于数据库性能。

ThingsBoard PE package download

Download ThingsBoard PE installation package for Windows: thingsboard-windows-setup-3.0.1pe.exe.

ThingsBoard PE service upgrade

Stop ThingsBoard service if it is running.

net stop thingsboard

Make a backup of previous ThingsBoard PE configuration located in <ThingsBoard install dir>\conf (for ex. C:\thingsboard\conf).
Run installation package thingsboard-windows-setup-3.0.1pe.exe.
Compare your old ThingsBoard configuration files (from the backup you made in the first step) with new ones.
Please make sure that you set database.ts.type parameter value (in the file <ThingsBoard install dir>\conf\thingsboard.yml) to “cassandra” instead of “sql” if you are using Cassandra database for timeseries data:

database:
  ts_max_intervals: "${DATABASE_TS_MAX_INTERVALS:700}" # Max number of DB queries generated by single API call to fetch telemetry records
  ts:
    type: "${DATABASE_TS_TYPE:sql}" # cassandra, sql, or timescale (for hybrid mode, DATABASE_TS_TYPE value should be cassandra, or timescale)

Finally, run upgrade.bat script to upgrade ThingsBoard to the new version.

NOTE Scripts listed above should be executed using Administrator Role.

NOTE: If you were using Cassandra database for entities data execute the following migration script:

C:\thingsboard>upgrade.bat --fromVersion=2.5.0PE-cassandra

Otherwise execute regular upgrade script:

C:\thingsboard>upgrade.bat --fromVersion=2.5.0

Start the service

若将 Redis 用于缓存，在启动 ThingsBoard 前需清空所有已存储的 key。

连接到您的 Redis 实例（或 container/pod，视部署方式而定），执行：

redis-cli flushall

注意：仅当 Redis 专门用于 ThingsBoard 时可使用此命令。若其他应用也使用 Redis，需定位 ThingsBoard 使用的数据库并仅清空该库。默认数据库 index 为 0，可通过 ThingsBoard 环境变量 REDIS_DB 配置。

redis-cli

select 0

flushdb

net start thingsboard
