Hi，Mr Wu We have used skywalking v6.0 Ga+ES v6.0 for more than half a year. And now we want to update skywalking to v6.6 with keeping data of service, instance, interface etc.
My steps below: 1.Install skywalking v6.6 + ES v6.6. The skywalking server is the same machine as v6.0 Ga. Agent keep using v6.0 Ga. 2.Import the data of service, instance, interface to the new ES server. 1) Only import the data of the indexes including network_address_inventory，service_inventory，service_instance_inventory，endpoint_inventory，register_lock from the old ES system. 2) Initialize the fields of the index in the new version but not existed in the old version. For the instance, the fields last_update_time, register_time, heartbeat_time of the index service_instance_inventory in the new version. 3. Keep the same as the field namespace of the configuration file in the ES, skywalking server, skywalking agent. 4. Close skywalking v6.0 GA 5. Run skywalking v6.6 In my testing process, the skywalking server is running successfully, and web UI is normal also(the data of service, instance, interface etc was showed). But there is no data from the agent. So I want to known there is any problem in my steps of skywalking updating. PLS help me. thanks jinf 在 2020-02-06 22:07:02，"Sheng Wu" <wu.sheng.841...@gmail.com> 写道： Hi, for mail list discussion, you should 1. Keep all discussion in English 2.
