People,
I'd like to know how can I safely apply the Exchange Server service pack or cumulative update to the Mailbox Server role (no DAG) without losing some email during the downtime and rolling back the snapshot ?
Can I do the following:
1. Stop all of the Exchange Server services.
2. Disconnect the vNIC in Mailbox server
3. Take VM snapshot
4. Apply the Exchange Server service Pack / Cumulative Update or Windows Update
5. Reboot
6. Reconnect the vNIC, if the server back online again with no issue, commit / delete the snapshot, if not, then disconnect the vNIC followed by roll back.
would that be make sense or supported from both Vmware and Microsoft http://www.vmware.com/files/pdf/exchange-2010-on-vmware-support-and-licensing-guide.pdf?
If yu have any other suggestion, please let me know here.
Thanks in advance.
