TitleConsiderations for upgrading Extreme Management Center to version 8.x (formerly Netsight)
Objective
Considerations for upgrading Extreme Management Center to version 8.x
Environment
  • Netsight
  • EMC
  • Extreme Management Center
Procedure
This article assumes that the customer has already upgraded their Netsight/EMC appliance to EMC 6.3 or higher. If this is a fresh install, this process is not relevant.
  • To upgrade to version 8.x, first the customer MUST be running Netsight Version  7.1.x.x. Prior versions of Netsight/Extreme Management Center and it's databases are NOT compatible with upgrading to 8.x.
  • Also, for Ubuntu/Linux based servers that deploy natively with our software, the OS needs to be upgraded, and packages must be installed so it needs connectivity to the internet.
  • Further, after these upgrades occur, the Server itself MUST reboot for the upgrades to take affect.
  • Estimates for downtime to do the upgrade are difficult to calculate, but likely significantly longer than previous upgrades.
  • Memory, CPU and disk space requirements and recommendations are significantly higher than previous versions. Based on the size of your network
  • The graphic below is representative of what the release notes for 8.x require for server hardware.

Additional notes

For Control and Analytics appliances  ( previously NAC and Purview) they must also be running 7.1.x.x to be detected by Extreme Management Center running 8.x. These appliances should be upgraded immediately following the completion of Extreme Management Centers upgrade to 8.x.
