After following some scarce information on setting up failover I found
on the web, and successfully failing over to a target SCR in my lab
environment, I'm kind of lost on how to get back to the original state
once the target is back online.

If the original source server was considered a total loss, I believe
the SCR would just be configured again. But what if for example the
internet connection or power in a WAN environment prevented users from
connecting to the source for a long enough period to justify failing
over. Once the connection to the source was re-established, how would
one syncronize the target with the original source? I'm hoping we
would not need to syncronize from scratch as that would entail either
the original server be sent from Atlanta to Houston or a large hard
drive be sent as our info store with be in the 130GB range.

Thanks
Max

Basically, what you do is you take the original source and clean it up.
Then configure it as a target for the new source (the original SCR target,
which is now the production system). Once replication to the new target has
caught up, you can suspend replication, and do an orderly activation going
the other way. See also,

for some additional info.

Hope this helps.

I ran into the same issue when testing this in our lab. What a PITA it was
to get back to the original server. We ran into issue where things wouldn't
install because it said the versions didn't match. Seems like the SCR
target shouldn't get any updates until after it becomes active. We had to
uninstall several patches and rollups to get it to work. Anyway, it was
very frustrating. I agree with you that it seems this was designed with the
original source becoming a total loss and rebuilt from scratch.
