title: Using Fabric Node SDK 1.4.x with Fabric 2.0
body: <p>We have just migrated to Fabric 2.0 and all of our components (peer, orderer, binaries) are at v2.0.0.</p>
  
  <p>Our Fabric Node SDK is still at v1.4.8 and most of its functions are working such as </p>
  
  <p><code>createChannel, updateChannel, installChaincode etc.</code> </p>
  
  <p>However, when I try to use <code>Channel.sendInstantiateProposal</code>, I get an error </p>
  
  <p><code>"Channel &lt;channel_name&gt; has been migrated to the new lifecycle. LSCC is now read only".</code></p>
  
  <p>I get the fact that this is likely a mismatch between the SDK and the Fabric components, however, is there any way to get this to work besides upgrading to Fabric Node SDK 2.0?</p>
  
  <p>The configtx.yaml file used to bring up the network has <code>capabilities all set to V2.0:true</code>. The notes indicate that V2.0 capabilities are non-backward compatible so I am assuming I cannot set them to V1.4 and still work with Fabric 2.0 components.</p>
  
  <p>Thanks</p>
