github.com/yacovm/fabric@v2.0.0-alpha.0.20191128145320-c5d4087dc723+incompatible/docs/source/upgrade_to_newest_version.rst (about) 1 Upgrading to the Newest Version of Fabric 2 ========================================= 3 4 At a high level, upgrading a Fabric network from v1.3 to v1.4 can be performed 5 by following these steps: 6 7 * Upgrade the binaries for the ordering service, the Fabric CA, and the peers. 8 These upgrades may be done in parallel. 9 * Upgrade client SDKs. 10 * (Optional) Upgrade the Kafka cluster. 11 12 To help understand this process, we've created the :doc:`upgrading_your_network_tutorial` 13 tutorial that will take you through most of the major upgrade steps, including 14 upgrading peers and orderers. We've included both a 15 script as well as the individual steps to achieve these upgrades. 16 17 Because our tutorial leverages the :doc:`build_network` (BYFN) sample, it has 18 certain limitations (it does not use Fabric CA, for example). Therefore we have 19 included a section at the end of the tutorial that will show how to upgrade 20 your CA, Kafka clusters, CouchDB, Zookeeper, vendored chaincode shims, and Node 21 SDK clients. 22 23 Because there are no new :doc:`capability_requirements` in v1.4, the upgrade 24 process does not require any channel configuration transactions. 25 26 ..
