SQL Migration from SQL2017 to SQL2022

AG1: Win OS 2016, SQL 2017

AG2: Win OS 2019, SQL 2022

We are trying to migrate database from AG1 to AG2 via distributed AG. As the database is on different version, the status of the db on AG2 will be in Synchronized/In Recovery mode which is not readable. Are there any ways to verify the data integrity of the database as its not readable?
