I recently migrated our LMS 2.6 server to another box. In order to do this I shut down the old box after I had all the backups that I needed. I renamed the new box the old server name and also gave it the same IP address.
Then I installed the software and the updates and restored the data. All of that went fine. After about an hour, all the connection lines went red.
I have verifed the settings and it looks like all the data and settings including the SNMP settings migrated over as well.
Not for sure what else to look for. Any held would be great.
