Hello.
</div>
<div class="default-style">
We have a product with 2 node clusters.
</div>
<div class="default-style">
Our current version is using Pacemaker 2.1.4 the new version will be using Pacemaker 2.1.6
</div>
<div class="default-style">
During upgrade failure it is possible that one node will come up with the new Pacemaker and work alone for a while.
</div>
<div class="default-style">
Then old node would later come up and try to join the cluster.
</div>
<div class="default-style">
This would fail due to the different feature-sets of the cluster nodes. The older feature-set would not be able to join the newer feature-set.
</div>
<div class="default-style">
</div>
<div class="default-style">
Question:
<br>
Is is possible to force new node with Pacemaker 2.1.6 to use older feature-set (3.15.0) for a while until second node is upgraded and is able to work with Pacemaker 2.1.6?

Thank you very much!
