Migration of Access Web App

Hi,
I would like to migrate my AWA to a 'new' Azure server.
But when migrating via Access desktop, I lost the following:
- relationship between the tables, in AWA it is called 'lookup'.
- field validation rules

Is there a way to solve this? FYI, I am not a migration expert

Thanks for your help!

the relationships are Access relations.
exporting tables ignores this. Youd have to build relations in Azure relations after the export.
