I upgrade my PHP in LAMP Ubuntu 14 server to PHP 7 following the tutorial - https://www.digitalocean.com/community/tutorials/how-to-upgrade-to-php-7-on-ubuntu-14-04
However after testing the application for 2 days, I wanted to downgrade it back to the original php version because of many unexpected errors in composer packages.

Would be helpful if anyone can share the details.

This work fine for me
From php5.6 to php7.0 : Apache: sudo a2dismod php5.6 ; sudo a2enmod php7.0 ; sudo service apache2 restart CLI: update-alternatives --set php /usr/bin/php7.0 from php7.0 to php5.6 : Apache: sudo a2dismod php7.0 ; sudo a2enmod php5.6 ; sudo service apache2 restart CLI: sudo update-alternatives --set php /usr/bin/php5.6
There’s any complication if i change the php version? my databases will remain?
