Can I change the domain of a server device?

Our company was purchased and we had to migrate all of our servers from one domain to another. So my question is how can I change the domain of all of our servers in OpManager? The "Rediscover Now" action appears to work and it shows the correct IP address. However, the credentials for the new domain fail so our monitoring no longer works. One strange thing I noticed is that the "Asset Details" shows the device name with the old domain!

The only way we've found to get around this problem is to delete the device and then rediscover it...but then we loose all the custom monitors in the process. If we have to do this for every server, it's going to take a LONG time. I hope there is a solution for this scenario.

Thanks,
