Upgrade From Previous Version

This file provides information on how to upgrade from VCL 2.1 to VCL 2.2. Please note it only applies for the upgrade from 2.1 to 2.2, this may or may not work for other versions.

The basic steps that will be preformed

• Shutdown httpd and vcld services
• Create backup of vcl database
• Update mysql schema
• Create backup of web directory
• Create backup of vcl directory
• Copy in 2.2 web directory make any changes
• Copy in 2.2 vcl directory make any changes/customizations
• Restart httpd and vcld services

Shutdown services

Shutdown the httpd and vcld services

service httpd stop or /etc/init.d/httpd stop
service vcld stop or /etc/init.d/vcld stop

Create a backup of vcl database

We will create a backup of the vcl database. This will provide a restore point if necessary.

mysql dump command

Update mysql schema

This step updates the mysql schema.

cd to vcl2.2 source directory
cd /<path to vcl 2.2 source> 

mysql vcl < mysql/update-2.2.sql

Update web code

This step will move the 2.1 web directory out of the way, so we can copy in the new web code base. In a later step we will migrate the changes from your 2.1 code base.

cd <your vcl web root>
i.e. cd /etc/httpd
mv vcl vcl_2.1_web

Update management node code

This step will move the 2.1 vcl code base out of the way, so we can cleanly copy in the new management node(MN) code.

cd <your vcl MN code path>
ie. cd /usr/local/
mv vcl vcl_2.1_management_node
