The case is that, we need to transfer data from one elasticsearch server A (in system A) to another elasticsearch server B (in system B). It's not simple like sycn / backup / dump as we also need to do some mapping. Index in server A and server B are with different fields and different mapping setting.
It's better to not write java codes or new micro-service to do this. I hope there could be some plugin, or any other tools/script that I can leverage.
Thanks very much in advance!
