Upgrade 10.10 Server

view story

http://ubuntuforums.org – I need to up upgrade an Ubuntu server 10.10. Of course this version is no longer supported EOL (apt-get update fails with 404s). Following Google, I have tried do-release-upgrade but that too fails also with 404s. Google suggests changing the urls in sources.list to old-release ... if I wish to update, but says I cannot then upgrade to new versions. Is there any path forward to upgrading 10.10? Thank you.
