I have server A with TDengine 3.0.2.4 installed, I want to migrate it to server B
but after I move the datafile to B and then change taos.cfg and dnode.json with proper connection information, the startup operation is failed
May I know the detail operation for that? I didn't find it in documentation.
TDengine uniquely marks a machine according to the hostname. For version 3.0, moving data files from machine A to machine B requires reconfiguring the hostname on machine B to the hostname on machine A.
Note 3.x is incompatible with the storage structure of previous versions 1.x and 2.x. You need to use migration tools or develop your own applications to export and import data.
