I have configured Distributed Availability Group (DAG) between two WSFC with the same SQL version (sql server 2016),
but now I want to configure the DAG with a different version of SQL Server (SQL Server 2016 and SQL server 2019), but arises error while configuration like 'Cannot open database 'test2' version 852. Upgrade the database to the latest version' and database status is Synchronized/In Recovery and it is mentioned that 'The database 'TEST' is marked RESTORING and is in a state that does not allow recovery to be run.' in SQL logs.
Two different things are mentioned in Microsoft documentation. I mark them in the following picture.
