2. Mirroring and replicating from the source to the original or
new source and failing over
1. Using the Full-Server Failover Manager , establish full-server protection from your
source to the original or new source. In the console, specify your source in the
Select source server field. Specify your original or new source that you built or
modified in step 1A or 1B above in the Select target server field. Use the same
connection settings that you used when protecting the source initially, although
you can select different settings for snapshots, compression, and so on.
2. Once you have established your connection, data will be mirrored from the source
to the target. Replication will keep the target up-to-date with the changes end-users
are continuing to make on the source.
Monitor the progress of the connection using
the Protection Status displayed in the right center of the Full-Server Failover
Manager.
3. Once the mirror is complete, determine when you want to perform failover. This will
require downtime, typically between 15 and 30 minutes depending on LAN or
WAN configurations and server processing capabilities.
4. Using the Full-Server Failover Manager, perform failover , verifying that the option
Shutdown source server if running is enabled. Use live data or a snapshot as
desired.
5. Monitor the failover percentage as shown in the Protection Status. At the end of
failover, the target will be rebooted automatically. After the reboot, the target will no
longer exist, since it will become the source.
After the reboot, users and other servers can resume normal operations after DNS/IP
updates have been propagated to them.
If desired, you can re-establish protection again for this source so that you are prepared
for the next emergency.
Note: If you want to reuse the same target hardware, you will have to remove the source
identity components from that server. You can use either method 1A or 1B above
to prepare a new target.
