I'm moving to a new server, better hardware and software, from Centos 5.8, php 5.2.17, MySQL 5.0 to Redhat 6.2, PHP 5.3.10 and MySQL 5.5.22, with double RAM. I have about 80 virtual servers. How do I backup and restore all virtual servers at once?
I was planning to setup a rsync to sync the home folder prior to migration, so when migrating I would backup everything except home dir. The backup restore will be much faster this way. Is this possible?
