The correct ways would be to purchase a licence or licences for the new store, do a backup, & restore on the new store.
Then contact us to help with the name change & re-licencing.
For all users : If you have multiple branches running with the same 4POS licences.....
Over the next couple of months - ALL 4POSUpgrades will be done via the internet & licences will be checked for validity.
If you have the same licences across multiple branches, the first branch will be able to upgrade & no others - ever again!
