The TiUP data is stored in the `.tiup` directory in the user's home directory. To migrate the control machine, you can take the following steps to copy the `.tiup` directory to the corresponding target machine:

1. Execute `tar czvf tiup.tar.gz .tiup` in the home directory of the original machine.
2. Copy `tip.tar.gz` to the home directory of the target machine.

3. Execute `tar xzvf tiup.tar.gz` in the home directory of the target machine.
4. Add the `.tiup` directory to the `PATH` environment variable.

If you use `bash` and you are a `tidb` user, you can add `export PATH=/home/tidb/.tiup/bin:$PATH` in `~/.bashr` and execute `source ~/.bashrc`. Then make corresponding adjustments according to the shell and the user you use.
