Assuming your xenapp environment in Windows VM servers, you can perform the upgrade of your Vcenter server from 5.5 to 6.0 and then perform the upgrade of ESXi host to 6.0
Please provide more information about your environment :
Number of ESXi host ?
Confirm if the ESXi host are managed by Vcenter server and ESXi host are in cluster ?
Hi
Thank you for the reply. we are having two independent vmware environments. one is vsphere 5.5 and the other is vsphere 6.0. In vsphere 5.5 we have a separate cluster for XenApp environment which is having 8 hosts managed by vCenter 5.5. we want to migrate all VM's from XenApp cluster to new XenApp Cluster having 12 hosts on vSphere 6.0 managed by vCenter 6.0. We donot have choice to upgrade vsphere 5.5 to 6.0, due to some internal limitations. We have common storage between XenApp cluster (vsphere 5.5) and New XenApp cluster (vsphere 6.0) and both environment is running on same subnet.
