On current 3.11 server issue the following and share back:
uname -an
php -v
mysql -V
du -h
Same on new server.
When you backup current site, don't save to local, but to a mount point on new server.
Commands issued from inside moodle code directory:
tar -cvf /mnt/clone/moodle-code-456+-$(date +%Y%m%d%-H%M%S).tar ../documentroot;
tar -cvf /mnt/clone/moodledata-data-min-456+-$(date +%Y%m%d%-H%M%S).tar /var/www/moodledata/filedir;
mysqldump -u root DBname > /mnt/clone/moodle-456+-db-$(date +%Y%m%d%-H%M%S).sql;
You would change version number above to your 311x.
