Does anyone have the video tutorial link for TiDB version 3.0?

username: TiDBer_yUoxD0vR

username: There shouldn’t be any. Starting from 5.X, certification 6.X.
|
username: It is recommended to upgrade in a timely manner and use the latest LTS version.
|
username: I suggest upgrading. We’ve been running 3.x for several years.
Did you follow the official documentation for the upgrade? Did you encounter any issues? How did you handle the rollback plan?
We will first set up a 6.5.0 system and migrate the data over. The old system will continue to be used. Once the verification is successful, we will switch over.
|
username: Are you using full backup + TiDB binlog for migration? After migrating directly from 3.x to 6.5.0, are there any syntax or parameter incompatibilities?

username: If you are still using version v3.0, I really recommend upgrading to version 6.1 or later. The new versions have significant improvements in stability, performance, and new features. Moreover, the official team only maintains the most recent versions, and the 3.x versions are no longer supported. From any perspective, you should consider upgrading. After upgrading, you can directly refer to the 6.x videos and documentation.
There’s no content about version 3.0 in this link. I’m worried that upgrading from version 3.0 to 6.1 is a big leap and there might be compatibility issues that we can’t detect at the moment. The program might run now, but issues could be triggered later.
Refer to it, 3 to 6 is indeed too large and requires thorough testing.
