    Description

      We don't repeat a attempt to copy the binary references and graph in the org.apache.jackrabbit.oak.segment.azure.tool.SegmentStoreMigrator now. It sometimes fails:

      12:08:28.955 [main] ERROR c.a.*.Main - Can't perform operation

      We can use runWithRetry() as for the segments.
