[TiDB Usage Environment] Production Environment
[TiDB Version] V4.0.14

TiDB was initially deployed using TiDB Ansible and later imported into TiUP, with the version upgraded to V4.0.14. Now, I want to use TiUP to upgrade the version to 6.5.2. However, it seems that the setup initially imported into TiUP is different from the one directly deployed by TiUP, with additional components like pump and different data directories, as shown in the image below.

I would like to ask if such a setup can be directly upgraded using TiUP? How are upgrades generally handled for setups imported from TiDB Ansible to TiUP?

You can test if tiup can control all nodes, then you can upgrade. Pump is a component of binlog, if you don’t need it, just scale it down.

How can I test if I can control the nodes? The tiup cluster display command works fine though.

Create a test version and try it out, it’s stable.

I suggest you try the entire operation process in a test environment first. Your version span is quite large, and there may be many incompatibilities. Try to encounter and resolve issues in the test environment as much as possible.
