VMware vCenter 6.7 U1 has recently been released. Last week I posted how to upgrade VCSA 6.7 to 6.7 Update 1, this post will walk you though upgrading VMware vCenter Server Appliance 6.5 to VCSA 6.7 Update 1!

When doing a VCSA version upgrade the upgrade process is much different, than going from say 6.7 to 6.7 U1. When going from 6.5 to 6.7 the upgrade is actually broken up into two stages.

The first stage involves deploying a brand new vCenter 6.7 appliance. Then the second stage will copy the data from your 6.5 VCSA into the newly deployed 6.7 VCSA from stage 1.

For a little while now we’ve been seeing RedHat Linux virtual machines performing poorly. Tasks would take considerably longer on the Linux VM’s then other Windows VM’s. After digging around I eventually found that RedHat has it’s own IO scheduler that runs in the background. On a physical box this wouldn’t be a big deal, but as a virtual machine everything is already being processed by VMware hypervisor. The fix, disable the IO Scheduler!

VMware vSphere 6.5 has been released as general available and earlier this week I posted about Installing VMware vCenter Server Appliance 6.5 as a new install, this post will walk through upgrading an existing vCenter Server Appliance 6.0 to 6.5!

Similar to a fresh VCSA 6.5 install, the VCSA 6.5 upgrade is also broken up into two stages. The first stage is deploying a new vCenter Server Appliance and the second stage is copying data from the 6.0 VCSA to the newly deployed 6.5 VCSA.
