Performing Failback
After your target has failed over and becomes your source, you can
stay with that configuration long term. However, in some instances,
it may be necessary or desired to go back to using the original
hardware after you have failed over. Use the following process to
failback to your original (or other) hardware.
1. Because your new source is on the network, you must make sure your original source is unique
on the network to avoid name and IP address conflicts. You have several options available for
achieving this.

Reinstall Windows using unique server information. This may be the best option if your original
source was a domain controller or running a name-specific application like Exchange.

Run a utility like Microsoft SysPrep to modify SIDs (security identifiers), IP addresses, and the
server name.

Manually make the original source unique by modifying IP addresses and the server name. If
your original source was a domain controller, you must also modify the SIDs.
2. Establish protection from your new source to your original source using the same process as
when you protected your original source. See Establishing Server Protection on page 5-1 for
details.
3. When the protection has been established from your new source to your original source, initiate
failover. See Initiating Failover on page 7-1 for details.
Once failover has completed, you will be back to your original hardware.
