Now that I’ve got my subdomain right, and all my v4 info transfered to v5, what do I do next?
Should I purge the v4 area? Should I leave it alone? Will it eventually get deleted with future upgrades to Invoice Ninja and I don’t need to worry about it?
If you want existing v4 invoice links to work you can enable forwarding on Settings > Account Management. If you no longer need you v4 data you can delete the account.
