We are still using M1.9 with PHP 5.2 and MySQL 5.1 . Our server provider(hostgator) has suggested to update to MySQL 5.5
My question is if it is safe (and recommended) to do such update for M1.9.
Another question is about the recommended procedure for database backup.
To make a backup every day as for courses? to save a copy outside the server?.....
Thanks in advance
