In the company I work for, we are migrating an old database to an Azure cloud, however this migration is being done with Python on a table-by-table basis, at the end of the migration of each table we have to check if the table in the old database has the same records as the new table practically manually and we always encounter many problems, however this verification process takes a long time and I would like to know if there is any resource that my team and I could use to carry out this process more quickly

I haven’t been able to test any tool yet because this old bank is very delicate and in order for us to use any new feature that involves it, everything must be very well thought out and tested beforehand, but I would like a tool or script that would carry out this entire process of validating the information contained. on the 2 banks automatically or more efficiently
