Posted by on in , | 5190 Views

This post is really a special post for me because it is my 250th post. We have already discussed about the upgrade from vCenter server appliance 5.5 to 5.5 Update 1. So you may be thinking why again repeated upgrade procedure for vCSA 5.1 to 5.5. Believe me both are entirely different step. We have upgraded vCSA 5.5 to vCSA 5.5 update 1 with the update option available with the admin page of the vCenter Server appliance but upgrading from vCSA 5.1 to 5.5 will not like other upgrades. It is to deploy the new appliance and reconfigure. This process will automates the movement of the database and other settings including network settings from older version of vCSA appliance (5.1) to new version of vCSA appliance (vCSA 5.5).once this movement is completed, new version of vCSA will be powered on with all existing data and older version of vCSA will be powered off. You can decommission the old vCSA appliance.

Procedure to Upgrade from vCenter Server Appliance 5.1 to 5.5

1. We have vCenter Server appliance 5.1 with latest build in our environment. To upgrade this vCSA 5.1 to vCenter server appliance 5.5 Update 1, Download and deploy the vCenter Server Appliance 5.5 Update 1. Take a look at the post Download link for vSphere 5.5 update 1 and other softwares.
