# Upgrades

Important - Please Read

Before commencing any upgrade, make sure you have a full backup of your existing system, including a schematic backup of your current database. In the event of something going wrong, you can always revert your database back and try again.
Upgrades are NOT available on versions of Maian Support prior to v2.0 or for TicketDesk Pro

Passwords - Please Read

If you are upgrading from a version older than 4.0, all passwords will be reset. In 4.0+ passwords are now stored using the PHP password API which uses bcrypt. This favours the less secure sha1 used in previous versions.
Once the upgrade has completed, you'll need to use the reset option to reset all staff passwords.
Account visitors will need to use the 'forgot password' option to reset their password. You can also batch reset the passwords via the admin interface and send out a broadcast message to let people know.
