I used PHP7 from the dotdeb packages for my install of Debian 8 Jessie. Now, I want to upgrade to Debian 9 Stretch (which has php7) and I want my Php7 package to be from Stretch and no more from dotdeb.
Is it possible, or should I keep php from dotdeb?
(Note: I don't want to uninstall php and reinstall it because I don't want to lose my configurations...)
apt-get remove
leaves the configuration files unless you use thepurge
command so your configs should be fine. – fcbsd Sep 06 '17 at 13:07
