Upgrade vCMP Guests(HA) from v11.3 to v12.1.2
Greetings people, I'm starting to plan on upgrading one of our vCMP Guests [Production F5's(HA Pair)] from v11.3.0 to v12.1.2. I need some assistance on risks involved or any precautions. Please see below procedure. Before upgrade: Backup .ucs and uplaod a qkview file onto ihealth site. Re-activate license on Host machines. We do have active service contract with F5. Actual Upgrade Procedure: Download both Base iso image and hotfix files. Upload them on to the standby F5. Install Base image file and then install the Hotfix file. Go to boot locations and select the new boot location where above images are installed and activate. Question here, Do i need to use the "Install configuration option"? What if I don't use it and just activate? Step 4 is done, failover and upgrade the other device & sync them. Did i miss anything critical in this process? These are production boxes and i'm so concerned about the upgrade to be successfull. Any help is greatly appreciated!_Thanks in advance_
