-# Why metrics indexes in Hour and Day precisions stop update after upgrade to 7.x?
+# Why do metrics indexes with Hour and Day precisions stop updating after upgrade to 7.x?
 
-This is an expected case when 6.x->7.x upgrade. 
-Read [Downsampling Data Packing feature](../setup/backend/backend-storage.md#downsampling-data-packing)
+This issue is to be expected with an upgrade from 6.x to 7.x. 
+See the [Downsampling Data Packing feature](../setup/backend/backend-storage.md#downsampling-data-packing)
 of the ElasticSearch storage.
 
-The users could simply delete all expired `*-day_xxxxx` and `*-hour_xxxxx`(`xxxxx` is a timestamp) indexes. 
-SkyWalking is using `metrics name-xxxxx` and `metrics name-month_xxxxx` indexes only.

 ### Reason
-Because the dependent Protocol Buffers v3.14.0 does not have an osx-aarch_64 version, Protocol Buffers Releases link: https://github.com/protocolbuffers/protobuf/releases, fortunately, mac m1 is compatible with the osx-x86_64 version, before this version is available for download, you need to manually specify the osx-x86_64 version.
+The dependent Protocol Buffers v3.14.0 does not come with an osx-aarch_64 version. You may find the osx-aarch_64 version at the Protocol Buffers Releases link here: https://github.com/protocolbuffers/protobuf/releases. Since Mac's M1 is compatible with the osx-x86_64 version, before this version is available for downloading, you need to manually specify the osx-x86_64 version.
 
-### Resolve
-We can add -Dos.detected.classifier=osx-x86_64 after the original compilation parameters, for example: `./mvnw clean package -DskipTests -Dos.detected.classifier=osx-x86_64`, After specifying, compile and run normally.
