Upgrade 

Upgrading from a version before 5.0.0 

Versions before 5.0.0 stored a single IP address per fe_users record in the column ip_address. jwauth 5.0.0 replaces this with the IP addresses relation described in Configuration. An upgrade wizard, Classes/Upgrade/MigrateIpAddressToMMUpgrade.php (identifier jwauth_migrateIpAddress), migrates every existing value into the new relation automatically - run it once via the Install Tool's "Upgrade Wizards" module, or on the command line:

ddev exec vendor/bin/typo3 upgrade:run jwauth_migrateIpAddress
Copied!

The wizard can safely be run more than once; it only migrates values that have not been migrated yet.
