Hi, @Rama Gilaka
First, the Azure SQL Database Migration Assistant does not support Progress Database.
And since what you're trying to do is completely custom, I think you can copy it into the table.
There are no custom migration guides.
Just create a standard data access application.
Another option is to use the Progress to SQL Server utility to migrate the Progress Database to SQL Server. It may be easy to migrate from here to Azure SQL Database.

However, I don't know the status of the latest Progress to SQL Server utility, so you should check it out.
