Hi,
Im currently learning Lync 2013 and have set up a 3 server pool. I am installing CU1 on each server and am trying to get my head around how to upgrade with no loss of service as I am using DNS Load Balancing. My I have the following set in DNS:
pool.mydomain.com > 192.168.0.30 (Lync-FE1)
pool.mydomain.com > 192.168.0.31 (Lync-FE2)
pool.mydomain.com > 192.168.0.32 (Lync-FE3)
What I did was installed CU1, rebooted and my client stayed connected, When I did the same on Lync-FE2 and rebooted my client disconnected. I guess my question is:
When a client first connects to a server (determined by DNS round robin), how can I upgrade to CU1 with no downtime?
Kind regards
