| 5 | +# In the initial release of OCP 3.4, paths for two objects, |
| 6 | +# User and EgressNetworkPolicy, inadvertantly changed. |
| 7 | +# This script migrates any of these resources created in |
| 8 | +# version of OCP 3.4 without the fix to the proper location |
| 9 | +# in etcd. Namely: |
| 10 | +# |
| 11 | +# identities -> useridentities |
| 12 | +# egressnetworkpolicies -> registry/egressnetworkpolicy |
