When we are migrating from one SQL Server Instance to another SQL Server Instance, often times we can migrate databases without any issue but the problem that occurs next is that the Logins for Users in each database are actually not migrated. The next problem is that we can create the same Logins but we need to input the password again, the thing is, sometimes it's not feasible to create same Logins with different password because this Logins might already be used by users for their processes. So in this part I want to show how to migrate SQL Server Instance Logins to new SQL Server Instance. This is very quick but helpful guide and this is official from Microsoft Documentation.

Change Data Capture (CDC) Change data capture utilizes the SQL Server Agent to log insertions, updates, and deletions occurring in a table. So, it makes these data changes accessible to be easily consumed using a relational format. The column data and essential metadata need to apply these change data to a target environment are captured for the modified rows and stored in change tables that mirror the column structure of the tracked source tables. Furthermore, table-valued functions are available for systematic access to this change data by consumers. Change data capture is used by application to track changes which happen in database. Some ETL apps like Kafka need this feature to be enabled when we want to stream data from one database to another destination. CDC is a feature at table level, so you need to enable this per each table if there are many tables in a database that need to be tracked. Here is the steps to setup CDC for tables in database.
