Upgrade from IJ 4.5.50 to 5.10.26

Hello Sir good evening, I want to ask for your support to migrate my Invoice Ninja 4.5.50 to 5.10.26 I was upgrading my hosting and I moved from old server to a new server with PHP8.0 and new versions unfortunately along the migration I lost the access to the Invoice Ninja 4.5.50 due the PHP Version was depreciated but the Software and Date base is uploaded into my new server, I created a new subdomain to migrate from the root server directory to a new subdomain usign the my domain name and new hosting service, please can you share with me a method to migrate or tool to help me with this process. Thank you in advance
Note: The new version is running on my new server without any issue.

Hi,

There’s a migration tool in the v4 app on Settings > Account Management

But if I can not have access to the old server how can I do that, everything was migrated from an old hosting server to a new hosting server

May I can do some manual process to migrate the date base and set up my new version of IN 5
Or how can i do to make to work the old version with php 8.0?

I suggest setting up a new install of the v4 app to use the migration tool.
