<div>Dear Johan</div>
<div><br>
</div>
<div>Basically we did just that last week, but we created a new cluster and put it new hosts with CentOS 7.1 and then migrated the machines, we also made the experience that Live Migration between clusters (in this Case Fedora 20 -> CentOS 7.1) does work if
not you have to reboot the hosts.</div>
<div><br>
</div>
<div>The last thing we did not due is migrated the hosted engine as well, but from my understanding it should basically be that same as migrating to a hosted engine – i will report once we go there</div>
<div><br>
</div>
<div>Cheers</div>

<div dir="ltr">Hi all,
<div><br>
</div>
<div>What would be the best upgrade path for upgrading a 3.5.2 cluster from C6 to C7?</div>
<div>Am I right in understanding that a cluster can have mixed hosts, but once a VM is on a C7 host, it cannot be migrated back to C6?</div>
