Upgrading from v4.
Move a version 4 installation onto Reward Loyalty 5 with a Reward Loyalty license key.
Reward Loyalty 5 uses a Reward Loyalty license key for activation and updates.
Get your key at rewardloyalty.co/download. Enter your existing purchase details there once, then use the Reward Loyalty license key inside the app.
Marketplace purchase codes are only used to retrieve your Reward Loyalty key.
That is all that changes. With your key in hand, update the way you always have: enter the key under License & Updates and click Update Now, or download the package at rewardloyalty.co/download with your license code and install it. See Updating for every method and the one that fits your hosting.
No other steps are required. The update runs its migrations and clears caches the same as any release.
