Our 2400 is underutilized there something in the log files I can look at to see if that's the case? System Information shows connection usage is 1.2 %. We received an email from SonicWall that our NSA 2400 is at end of life, and we are choosing between moving to the NSA 2600 or the TZ 600. Looks like migration from NSA 220, 240, 450M, and 2400 to the TZ 600 is supported. That link is from before Dell spun off SonicWall. Anyone had any experience with this? I currently have a support ticket in with Dell to hopefully get a definitive answer! This link shows it's not supported, but if I use the migration tool on it would appear that it is. My only concern is exporting/importing configuration files from the 3500 to the 600. The more I look at the TZ 600 the more appealing it looks, especially considering we can save some money on the Comprehensive Gateway Security Suite subscription. I know this is kind of an old post but I am considering moving from an NSA 3500 to an NSA 2600 or possibly the TZ 600.
