     apt-get dist-upgrade is what's necessary to change release - as the 
name means -, eg Wheezy to Jessie or Jessie to Ascii. This is why it 
should rarely be used, and only after carefully editing sources.list. 
It's a jump into the new. Dist-upgrade always worked fine for me and I 
consider this as one of the greatest achievements of Debian's package 
management technology.


     I would recommend some clean-up before the jump. For example I 
would uninstall things like mysql server which doesn't recognize any 
priviledge to root. Also Debian tended to install a lot of packages the 
user doesn't want and even doesn't know, so better get them out before 
the dist-upgrade


     For all the rest of the life of the release, upgrading is the job 
of apt-get upgrade / aptitude / synaptic. Don't use dist-upgrade for that.


     I installed most Devuan Jessie machines I run currently by 
dist-upgrading from Wheezy. No issue.


     For everyday I use Synaptic, or sometimes apt-get upgrade; I feel 
more on control with synaptic.
