If App developers who are using self-developed or third-party instant messaging services want to access instant messaging Chat, they need to consider migration. Chat proposes a simplified version of the migration solution based on different scenarios. In this way, the migration workload is only slightly more than the newly accessed Tencent Cloud ChatSDK. Compared with the full version of the smooth migration, the workload is greatly reduced.
Precondition
Historical messages from 1-3 months ago can be abandoned
Migration Plan
The main process is as follows:
1. Simultaneously integrate Tencent Cloud chat SDK and old SDK, and both initialization and login SDK must be done.
2. Double write at the SDK level for all Chat related write operations.
3. Default external display (actual display) of old SDK.
4. Control which SDK is displayed on the terminal side through backend configuration and grayscale scaling.
5. Double write in parallel for a period of time, after observing that there are no issues, switch all to the new Tencent Cloud SDK.
