I need to migrate from the tuned Ubuntu Server 8.04 LTS x32 to new OS Ubuntu Server 10.04 LTS x64. Our team are use this server for collaboration. Now installed: Samba server, Apache, Subversion, Mediawiki, Bugzilla, VirtualBox with guest OS'es. New installation should be on the same HDD as the old one. Server should be offline no more then couple hours.
- How can I properly migrate without loosing all my system settings(network,mail, etc.)? Can I copy all settings from
/etcto the new OS? Can I copy user settings from
/hometo the new OS?
- Is there a way to find all distinctions from clean installation so I could apply them to the new OS?
- How to keep the same set of installed packages?
- Is there a tool to automate migration?
