I recommend making a backup with Clonezilla at this point. After that, you could remove apache and purge unused/uninstalled packages but you don't have to.
Hi ryecoaaron,
Actually I am running OMV as KVM VM and first step of always having a valid backup specially before making some bigger changes is already done.
Just to avoid some unnecessary complications I would like to know what can be truly safely removed...
This are .old files/dirs in / but what else?
I can't just try my best luck with all stopped services, even for apache that was replaced I am not completely sure if it can be removed. Maybe some plugin will try to fire it up at some point and will crash or something because it will be missing.
Maybe the best idea is to clean/purge obvious and leave everything else as is. Services are already stopped after all... 
Thanks for answer,
iks
You can remove apache. If a plugin and/or the system uses it, it will try and remove something you want to keep. So, just pay attention to what it is trying to remove.
On my systems, I removed apache, squeeze kernels (2.6.32 and 3.2 kernel with bp in name), and any uninstalled package. The uninstall packages will be show by: dpkg -l | grep ^rc
As for the .old files, move them to a temporary folder (not /tmp) and reboot. If it needed them, you can move it right back.
Other than that, most packages are upgraded. So, there isn't a lot to remove.
If I may suggest using aptitude ?
I have installed it with:
apt-get install aptitudethen select:
"Obsolete and Locally Created Packages"to show the obsolete packages to remove.
just my 2 cents.
You might try this too:
apt-get autoremove
