 ===========

+ **N.B. Version 2.6.5 upgrade to 3.1.1 is upgrading etcd store to etcdv3**
+ If you create automated backups of etcdv2 please switch for creating etcdv3 backups, as kubernetes and calico now uses etcdv3
+ After migration you can check `/tmp/calico_upgrade/` directory for converted items to etcdv3.
+ **PLEASE TEST upgrade before upgrading production cluster.**
