If your license key starts with 917, the M-Files Server will remain to function as this is a perpetual key that is being phased out. However, upgrades are no longer possible as the released version at the time of the key being generated is the latest version the key will activate. In other words, if your key was generated when M-Files 11.3 was released, you cannot upgrade to a newer version above 11.3.
If your license key starts with 919, your vaults will cease to function until a new key is installed. This key activates M-Files Online which is a subscription-based setup. Be sure to install a new key before this date is reached to avoid interruption of the system.
