NAMEoc adm migrate etcd−ttl − Attach keys to etcd v3 leases to assist in etcd v2 migrations

SYNOPSISoc adm migrate etcd−ttl [OPTIONS]

DESCRIPTIONAttach etcd keys to v3 leases to assist in migration from etcd v2 This command updates keys to associate them with an etcd v3 lease. In etcd v2, keys have an innate TTL field which has been altered in the new schema. This can be used to set a timeout on keys migrated from the etcd v2 schema to etcd v3 is intended to be used after that upgrade is complete on events and access tokens. Keys that are already attached to a lease will be ignored. If another user modifies a key while this command is running you will need to re−run. Any resource impacted by this command will be removed from etcd after the lease−duration expires. Be VERY CAREFUL in which values you place to −−ttl−keys−prefix, and ensure you have an up to date backup of your etcd database.
