Easy Migration between OS
#1
Hello,

I hope i am asking this question in the right place. I was thinking of reinstalling a VPS OS. I wish to switch from debian 8 to debian 8 minimal, keeping the same software configuration stack. i.e. I would like to conserve the services installed by me along with their configuration while moving to lighter OS.

Any ideas?

A minimal distro is essentially the same as a "full" distro, just without some packages, that you could always install yourself anyway should they be needed.
So to go from "full" to "minimal" so to speak, essentially you will just be removing the non-critical packages that you don't use, or that other packages don't depend on.

There's a page on the Debian Wiki with a few non-critical packages you could remove to lighten the system.

Do you need further help with this?

There are always more ways to get it smaller. Look at packages, what do they do and what do they depend on or what does depend on them. If you don't need them and nothing else needs them you can then simply uninstall them. Like who needs "eject" in a VPS (this example is rather poor though as the package is rather small and wouldn't gain much free space). Another example would be the "isc-dhcp-client*" packages on a OpenVZ VPS. Since OpenVZ always configures the network of the VPS static and will always overwrites the configuration file if user changes are made a DHCP client is totally unnecessary.

https://packages.debian.org/ is generally a great page to find the package and its description plus dependencies and so on.

I usually do "dpkg --get-selections > installed_packages.txt", then go through the list of the installed packages and look for packages that I know that I don't need them and which I can remove without breaking the OS.
