environment:

1. riak kv cluster with 10 nodes
2. riak kv 2.9.10 on centos 7
3. every node have about 1.6T in leveldb folder

problem:
our app get so many not found errors after cluster in new data center.
And found so many warning message in riak/console.log like below:

riak_kv_vnode:log_key_amnesia:4493 Inbound clock entry for <<157,70,93,96,209,34,165,36>> in <<"spgs_orderlog_10_1731_0">>/<<"20135476791">> greater than local.Epochs: {In:70316435 Local:0}. Counters: {In:1 Local:0}

operations:
we are migration data center last month, and use below steps as the migration solution for riak cluster

1. stop on node named [email protected] on data center A
2. rsync the cluster_meta,ensembles,ring,leveldb folders to [email protected] on data center B
   3, change the /etc/hosts config file to keep the network working
   4, start [email protected] on data center B, waiting riak transfers done, and then repeat #1 – #3 steps

And my question is:
Did my migration solution correctly?
And what can I do to fix the not found errors?
