Platform upgradation

I'm planing for upgrading an I2800 series HA pair to i3800 series platform. What are all steps and precautions I should follow ?

Hi ,

 

on a very high level:

  1. Perform a basic config on the new hardware. Activate License and have HTTPS / SSH access. Basically run the setup utility till "Platform". Then stop with "Finished".
  2. Have old and new hardware on the same BIG-IP version.
  3. Set the Masterkey on the new hardware (see K9420: Installing UCS files containing encrypted passwords or passphrases (11.5.x and later))
  4. Create backup on the old hardware.
  5. Restore the backup on the new platfrom with the no-license option.

 

Due to the little information you gave, it is difficult to go into more details. You didn't tell us whether or not you have a cluster, or you want to change / keep the management and self-ip adresses or other network configurations.

 

A word of caution: If you have never done this before, you should consider to hire a consulting company to assist you.

In addition to what Daniel wrote, it's also possible to add the new i3800 appliances to the existing cluster. Make sure you sync the configuration to the new members. Then failover to one of the new units and remove the i2600 appliances from the cluster. When using this approach it's also key to use the same BIG-IP version, but you don't need to worry about the masterkeys.
