You could, but this isn't something many here would be able and experienced to help with.
You will/may also have to mess around with the license management between the two servers. i.e. delicense the inactive server and re-licence the active server.
The FoE also copies over logfiles and misc other configuration files between the servers, so you would have to do that manually.
[note: as my SQL servers are fairly beefy we use of SQLserver native asynchronous mirroring to copy the data to our secondary SQL server continually]
Thanks for the reply Richard. It seems our tests are indicating this would work. We'll continue pursuing this unitl (or whether) we hit an issue with it. Thanks again.
