Updating Ubuntu server from 8.10 to 10.04
I'm in a plan to upgrade ubuntu 8.10 vbox vm servers to LTS(obviously 10.04) as 8.10 has no support. As far as I know I'll be executing the following to upgrade:
apt-get install update-manager-core do-release-upgrade
anybody could tell me how could I upgrade a ubuntu server from alternate iso image(Is the alternate iso image used for desktop editons the same used for servers?)?
I heard it's possible to upgrade an LTS directly to another LTS and how could I do this after upgrading 8.10 to 9.04 then directly to 10.04 skipping 9.10?
8.10 servers are hosting many services/applications/databases like apache2, tomcat6, ldap, mysql, cvs... and I'm not sure that all of them work as ever after the upgrade. If there is any precautions that I've to following before upgrading, please anyone let me know(ofcourse backup and I'm not going to take backup as I will be trying this on a copy of vdi/vmdk vms)
