I have a scenario in which there are:
3 x Ex2010 Mailbox Server in DAG (on vSphere cluster)
2 x HT and CAS with NLB configured (on Hyper-V cluster)
2 x UM server
and also hybrid configuration.
I am not really an expert in O365 / hybrid configurations.
As per refresh cycle, I have to move VMs from existing Hyper-v and vmware (all above roles) to new vSphere cluster.
For Mailbox I have planned to create new MailboxServer VMs with new name,IP and add them in DAG, add a copy of each databases to new VMs, remove copy from old VMs and uninstall Exchange from old VMs.
Also will be updating the RPCClientaccessserver, move arbitration mailbox
For HT-CAS and UM, I am planning to use vmware converter to move VMs from hyper-V one at a time to vSphere cluster.
I believe I will have to retain the mac address of NICs from hyper-v vms
I am here for some advice, suggestions and caution I must take, specially with hybrid setup.
appreciate your comments.
