12 oc adm migrate etcd-ttl [OPTIONS]
13
17 Attach etcd keys to v3 leases to assist in migration from etcd v2
18 This command updates keys to associate them with an etcd v3 lease. In
21 etcd v2, keys have an innate TTL field which has been altered in the
22 new schema. This can be used to set a timeout on keys migrated from the
23 etcd v2 schema to etcd v3 is intended to be used after that upgrade is
24 complete on events and access tokens. Keys that are already attached to
25 a lease will be ignored. If another user modifies a key while this com‐
26 mand is running you will need to re-run.
27 Any resource impacted by this command will be removed from etcd after
30 the lease-duration expires. Be VERY CAREFUL in which values you place
31 to --ttl-keys-prefix, and ensure you have an up to date backup of your
32 etcd database.
